CC -!- FUNCTION: Tumor suppressor that is a key regulator of the G1/S
CC transition of the cell cycle (PubMed:10499802). The hypophosphorylated
CC form binds transcription regulators of the E2F family, preventing
CC transcription of E2F-responsive genes (PubMed:10499802). Both
CC physically blocks E2Fs transactivating domain and recruits chromatin-
CC modifying enzymes that actively repress transcription
CC (PubMed:10499802). Cyclin and CDK-dependent phosphorylation of RB1
CC induces its dissociation from E2Fs, thereby activating transcription of
CC E2F responsive genes and triggering entry into S phase
CC (PubMed:10499802). RB1 also promotes the G0-G1 transition upon
CC phosphorylation and activation by CDK3/cyclin-C (PubMed:15084261).
CC Directly involved in heterochromatin formation by maintaining overall
CC chromatin structure and, in particular, that of constitutive
CC heterochromatin by stabilizing histone methylation. Recruits and
CC targets histone methyltransferases SUV39H1, KMT5B and KMT5C, leading to
CC epigenetic transcriptional repression. Controls histone H4 'Lys-20'
CC trimethylation. Inhibits the intrinsic kinase activity of TAF1.
CC Mediates transcriptional repression by SMARCA4/BRG1 by recruiting a
CC histone deacetylase (HDAC) complex to the c-FOS promoter. In resting
CC neurons, transcription of the c-FOS promoter is inhibited by BRG1-
CC dependent recruitment of a phospho-RB1-HDAC1 repressor complex. Upon
CC calcium influx, RB1 is dephosphorylated by calcineurin, which leads to
CC release of the repressor complex (By similarity).
CC {ECO:0000250|UniProtKB:P13405, ECO:0000250|UniProtKB:P33568,
CC ECO:0000269|PubMed:10499802, ECO:0000269|PubMed:15084261}.
CC -!- FUNCTION: (Microbial infection) In case of viral infections,
CC interactions with SV40 large T antigen, HPV E7 protein or adenovirus
CC E1A protein induce the disassembly of RB1-E2F1 complex thereby
CC disrupting RB1's activity. {ECO:0000269|PubMed:1316611,

CC -!- SUBUNIT: Interacts with ATAD5. Interacts with PRMT2, CDK1 and CDK2 (By
CC similarity). The hypophosphorylated form interacts with and sequesters
CC the E2F1 transcription factor (PubMed:8336704, PubMed:20940255).
CC Interacts with heterodimeric E2F/DP transcription factor complexes
CC containing TFDP1 and either E2F1, E2F3, E2F4 or E2F5, or TFDP2 and
CC E2F4. The unphosphorylated form interacts with EID1, ARID3B, KDM5A,
CC SUV39H1, MJD2A/JHDM3A and THOC1. Interacts with the N-terminal domain
CC of TAF1. Interacts with SNW1, AATF, DNMT1, LIN9, LMNA, KMT5B, KMT5C,
CC PELP1, UHRF2 and TMPO-alpha. May interact with NDC80. Interacts with
CC GRIP1 and UBR4. Interacts with ARID4A and KDM5B. Interacts with E4F1
CC and LIMD1. Interacts with SMARCA4/BRG1 AND HDAC1 (By similarity).
CC Interacts with PSMA3 and USP4. Interacts (when methylated at Lys-860)
CC with L3MBTL1. Interacts with CHEK2; phosphorylates RB1. Interacts with
CC CEBPA (PubMed:15107404). P-TEFB complex interacts with RB1; promotes
CC phosphorylation of RB1 (PubMed:12037672). Interacts with RBBP9; the
CC interaction disrupts RB1 binding to E2F1 (By similarity). Interacts
CC with KAT2B/PCAF and EP300/P300 (By similarity). Interacts with PAX5
CC (PubMed:10197586). {ECO:0000250|UniProtKB:P13405,

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:20940255}.
CC Note=During keratinocyte differentiation, acetylation by KAT2B/PCAF is
CC required for nuclear localization. {ECO:0000269|PubMed:20940255}.
CC -!- TISSUE SPECIFICITY: Expressed in the retina. Expressed in foreskin
CC keratinocytes (at protein level) (PubMed:20940255).
CC {ECO:0000269|PubMed:20940255}.
CC -!- DOMAIN: The Pocket domain binds to the threonine-phosphorylated domain
CC C, thereby preventing interaction with heterodimeric E2F/DP
CC transcription factor complexes.
CC -!- PTM: Phosphorylated by CDK6 and CDK4, and subsequently by CDK2 at Ser-
CC 567 in G1, thereby releasing E2F1 which is then able to activate cell
CC growth. Dephosphorylated at the late M phase. SV40 large T antigen, HPV
CC E7 and adenovirus E1A bind to the underphosphorylated, active form of
CC pRb. Phosphorylation at Thr-821 and Thr-826 promotes interaction
CC between the C-terminal domain C and the Pocket domain, and thereby
CC inhibits interactions with heterodimeric E2F/DP transcription factor
CC complexes. Dephosphorylated at Ser-795 by calcineruin upon calcium
CC stimulation. CDK3/cyclin-C-mediated phosphorylation at Ser-807 and Ser-
CC 811 is required for G0-G1 transition. Phosphorylated by CDK1 and CDK2
CC upon TGFB1-mediated apoptosis. {ECO:0000269|PubMed:10499802,
CC ECO:0000269|PubMed:8114739}.
CC -!- PTM: N-terminus is methylated by METTL11A/NTM1 (By similarity).
CC Monomethylation at Lys-810 by SMYD2 enhances phosphorylation at Ser-807
CC and Ser-811, and promotes cell cycle progression. Monomethylation at
CC Lys-860 by SMYD2 promotes interaction with L3MBTL1. {ECO:0000250,
CC ECO:0000269|PubMed:15084261, ECO:0000269|PubMed:15809340,

CC ECO:0000269|PubMed:22787429}.
CC -!- PTM: Acetylated during keratinocyte differentiation. Acetylation at
CC Lys-873 and Lys-874 regulates subcellular localization. Can be
CC deacetylated by SIRT1. {ECO:0000269|PubMed:20940255}.
CC -!- DISEASE: Childhood cancer retinoblastoma (RB) [MIM:180200]: Congenital
CC malignant tumor that arises from the nuclear layers of the retina. It
CC occurs in about 1:20'000 live births and represents about 2% of
CC childhood malignancies. It is bilateral in about 30% of cases. Although
CC most RB appear sporadically, about 20% are transmitted as an autosomal
CC dominant trait with incomplete penetrance. The diagnosis is usually
CC made before the age of 2 years when strabismus or a gray to yellow
CC reflex from pupil ('cat eye') is investigated.
CC {ECO:0000269|PubMed:10671068, ECO:0000269|PubMed:11524739,

CC ECO:0000269|PubMed:9973307}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- DISEASE: Bladder cancer (BLC) [MIM:109800]: A malignancy originating in
CC tissues of the urinary bladder. It often presents with multiple tumors
CC appearing at different times and at different sites in the bladder.
CC Most bladder cancers are transitional cell carcinomas that begin in
CC cells that normally make up the inner lining of the bladder. Other
CC types of bladder cancer include squamous cell carcinoma (cancer that
CC begins in thin, flat cells) and adenocarcinoma (cancer that begins in
CC cells that make and release mucus and other fluids). Bladder cancer is
CC a complex disorder with both genetic and environmental influences.
CC Note=Disease susceptibility is associated with variants affecting the
CC gene represented in this entry.
CC -!- DISEASE: Osteogenic sarcoma (OSRC) [MIM:259500]: A sarcoma originating
CC in bone-forming cells, affecting the ends of long bones. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- SIMILARITY: Belongs to the retinoblastoma protein (RB) family.
