CC   -!- FUNCTION: Ser/Thr-kinase component of cyclin D-CDK4 (DC) complexes that
CC       phosphorylate and inhibit members of the retinoblastoma (RB) protein
CC       family including RB1 and regulate the cell-cycle during G(1)/S
CC       transition. Phosphorylation of RB1 allows dissociation of the
CC       transcription factor E2F from the RB/E2F complexes and the subsequent
CC       transcription of E2F target genes which are responsible for the
CC       progression through the G(1) phase. Hypophosphorylates RB1 in early
CC       G(1) phase. Cyclin D-CDK4 complexes are major integrators of various
CC       mitogenenic and antimitogenic signals. Also phosphorylates SMAD3 in a
CC       cell-cycle-dependent manner and represses its transcriptional activity.
CC       Component of the ternary complex, cyclin D/CDK4/CDKN1B, required for
CC       nuclear translocation and activity of the cyclin D-CDK4 complex (By
CC       similarity). {ECO:0000250|UniProtKB:P11802}.

CC   -!- ACTIVITY REGULATION: Both phosphorylation at Thr-172 and binding of a
CC       D-type cyclin are necessary for enzymatic activity. Full activation of
CC       the cyclin-D-CDK4 complex appears to require other factors such as
CC       recruitment of the substrate via a substrate recruitment motif, and/or
CC       formation of the CDKN1B ternary complex. Inhibited by INK4 family
CC       members. In resting cells, the non-tyrosine-phosphorylated form of
CC       CDKN1B prevents phosphorylation at Thr-172 and inactivation, while, in
CC       proliferating cells, tyrosine phosphorylation of CDKN1B allows
CC       phosphorylation of Thr-172 of CDK4 and subsequent activation.
CC       {ECO:0000250|UniProtKB:P11802}.
CC   -!- SUBUNIT: Component of the D-CDK4 complex, composed of CDK4 and some D-
CC       type G1 cyclin (CCND1, CCND2 or CCND3). Interacts directly in the
CC       complex with CCND1, CCND2 or CCND3. Interacts with SEI1 and ZNF655.
CC       Forms a ternary complex, cyclin D-CDK4-CDKN1B, involved in modulating
CC       CDK4 enzymatic activity. Interacts directly with CDKN1B (phosphorylated
CC       on 'Tyr-88' and 'Tyr-89'); the interaction allows assembly of the
CC       cyclin D-CDK4 complex, Thr-172 phosphorylation, nuclear translocation
CC       and enhances the cyclin D-CDK4 complex activity. CDK4 activity is
CC       either inhibited or enhanced depending on stoichiometry of complex. The
CC       non-tyrosine-phosphorylated form of CDKN1B prevents T-loop
CC       phosphorylation of CDK4 producing inactive CDK4. Interacts
CC       (unphosphorylated form) with CDK2. Also forms ternary complexes with
CC       CDKN1A or CDKN2A. Interacts directly with CDKN1A (via its N-terminal);
CC       the interaction promotes the assembly of the cyclin D-CDK4 complex, its
CC       nuclear translocation and promotes the cyclin D-dependent enzyme
CC       activity of CDK4. Interacts with CCND1; the interaction is prevented
CC       with the binding of CCND1 to INSM1 during cell cycle progression.
CC       Probably forms a complex composed of chaperones HSP90 and HSP70, co-
CC       chaperones CDC37, PPP5C, TSC1 and client protein TSC2, CDK4, AKT, RAF1
CC       and NR3C1; this complex does not contain co-chaperones STIP1/HOP and
CC       PTGES3/p23. Interacts with CEBPA (when phosphorylated). Interacts with
CC       FNIP1 and FNIP2. {ECO:0000250|UniProtKB:P11802,
CC       ECO:0000250|UniProtKB:P30285}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P11802}. Nucleus
CC       {ECO:0000250|UniProtKB:P11802}. Nucleus membrane
CC       {ECO:0000250|UniProtKB:P11802}. Note=Cytoplasmic when non-complexed.
CC       Forms a cyclin D-CDK4 complex in the cytoplasm as cells progress
CC       through G(1) phase. The complex accumulates on the nuclear membrane and
CC       enters the nucleus on transition from G(1) to S phase. Also present in
CC       nucleoli and heterochromatin lumps. Colocalizes with RB1 after release
CC       into the nucleus (By similarity). {ECO:0000250|UniProtKB:P11802}.
CC   -!- PTM: Phosphorylation at Thr-172 is required for enzymatic activity.
CC       Phosphorylated, in vitro, at this site by CCNH-CDK7, but, in vivo,
CC       appears to be phosphorylated by a proline-directed kinase. In the
CC       cyclin D-CDK4-CDKN1B complex, this phosphorylation and consequent CDK4
CC       enzyme activity, is dependent on the tyrosine phosphorylation state of
CC       CDKN1B. Thus, in proliferating cells, CDK4 within the complex is
CC       phosphorylated on Thr-172 in the T-loop. In resting cells,
CC       phosphorylation on Thr-172 is prevented by the non-tyrosine-
CC       phosphorylated form of CDKN1B (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr
CC       protein kinase family. CDC2/CDKX subfamily. {ECO:0000305}.
