CC -!- FUNCTION: Integrins alpha-1/beta-1, alpha-2/beta-1, alpha-10/beta-1 and
CC alpha-11/beta-1 are receptors for collagen. Integrins alpha-1/beta-1
CC and alpha-2/beta-2 recognize the proline-hydroxylated sequence G-F-P-G-
CC E-R in collagen. Integrins alpha-2/beta-1, alpha-3/beta-1, alpha-
CC 4/beta-1, alpha-5/beta-1, alpha-8/beta-1, alpha-10/beta-1, alpha-
CC 11/beta-1 and alpha-V/beta-1 are receptors for fibronectin. Alpha-
CC 4/beta-1 recognizes one or more domains within the alternatively
CC spliced CS-1 and CS-5 regions of fibronectin. Integrin alpha-5/beta-1
CC is a receptor for fibrinogen. Integrin alpha-1/beta-1, alpha-2/beta-1,
CC alpha-6/beta-1 and alpha-7/beta-1 are receptors for lamimin. Integrin
CC alpha-6/beta-1 (ITGA6:ITGB1) is present in oocytes and is involved in
CC sperm-egg fusion. Integrin alpha-4/beta-1 is a receptor for VCAM1 and
CC recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-9/beta-1 is a
CC receptor for VCAM1, cytotactin and osteopontin. It recognizes the
CC sequence A-E-I-D-G-I-E-L in cytotactin. Integrin alpha-3/beta-1 is a
CC receptor for epiligrin, thrombospondin and CSPG4. Integrin alpha-
CC 3/beta-1 provides a docking site for FAP (seprase) at invadopodia
CC plasma membranes in a collagen-dependent manner and hence may
CC participate in the adhesion, formation of invadopodia and matrix
CC degradation processes, promoting cell invasion. Alpha-3/beta-1 may
CC mediate with LGALS3 the stimulation by CSPG4 of endothelial cells
CC migration. Integrin alpha-V/beta-1 is a receptor for vitronectin. Beta-
CC 1 integrins recognize the sequence R-G-D in a wide array of ligands.
CC When associated with alpha-7/beta-1 integrin, regulates cell adhesion
CC and laminin matrix deposition. Involved in promoting endothelial cell
CC motility and angiogenesis. Involved in osteoblast compaction through
CC the fibronectin fibrillogenesis cell-mediated matrix assembly process
CC and the formation of mineralized bone nodules. May be involved in up-
CC regulation of the activity of kinases such as PKC via binding to KRT1.
CC Together with KRT1 and RACK1, serves as a platform for SRC activation
CC or inactivation. Plays a mechanistic adhesive role during telophase,
CC required for the successful completion of cytokinesis (By similarity).
CC ITGA4:ITGB1 binds to fractalkine (CX3CL1) and may act as its coreceptor
CC in CX3CR1-dependent fractalkine signaling. ITGA4:ITGB1 and ITGA5:ITGB1
CC bind to PLA2G2A via a site (site 2) which is distinct from the
CC classical ligand-binding site (site 1) and this induces integrin
CC conformational changes and enhanced ligand binding to site 1.
CC ITGA5:ITGB1 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-
CC D-dependent cell adhesion to FBN1. ITGA5:ITGB1 is a receptor for IL1B
CC and binding is essential for IL1B signaling (By similarity).
CC ITGA5:ITGB3 is a receptor for soluble CD40LG and is required for
CC CD40/CD40LG signaling (By similarity). Plays an important role in
CC myoblast differentiation and fusion during skeletal myogenesis (By
CC similarity). {ECO:0000250|UniProtKB:P05556,
CC ECO:0000250|UniProtKB:P07228, ECO:0000250|UniProtKB:P09055}.
CC -!- SUBUNIT: Interacts with seprase FAP (seprase); the interaction occurs
CC at the cell surface of invadopodia membrane in a collagen-dependent
CC manner (By similarity). Heterodimer of an alpha and a beta subunit.
CC Beta-1 associates with either alpha-1, alpha-2, alpha-3, alpha-4,
CC alpha-5, alpha-6, alpha-7, alpha-8, alpha-9, alpha-10, alpha-11 or
CC alpha-V. ITGA6:ITGB1 is found in a complex with CD9; interaction takes
CC place in oocytes and is involved in sperm-egg fusion. Binds LGALS3BP
CC and NMRK2, when associated with alpha-7, but not with alpha-5.
CC Interacts with FLNA, FLNB, FLNC and RANBP9. Interacts with KRT1 in the
CC presence of RACK1 and SRC. Interacts with JAML; integrin alpha-4/beta-1
CC may regulate leukocyte to endothelial cells adhesion by controlling
CC JAML homodimerization. Interacts with RAB21. Interacts (via the
CC cytoplasmic region) with RAB25 (via the hypervariable C-terminal
CC region). Interacts with MYO10. Interacts with ITGB1BP1 (via C-terminal
CC region); the interaction is a prerequisite for focal adhesion
CC disassembly. Interacts with TLN1; the interaction is prevented by
CC competitive binding of ITGB1BP1. Interacts with ACAP1; required for
CC ITGB1 recycling. Interacts with ASAP3. Interacts with FERMT2; the
CC interaction is inhibited in presence of ITGB1BP1. Interacts with DAB2.
CC Interacts with FGR and HCK. Isoform 2 interacts with alpha-7A and
CC alpha-7B in adult skeletal muscle. Isoform 2 interacts with alpha-7B in
CC cardiomyocytes of adult heart. Interacts with EMP2; the interaction may
CC be direct or indirect and ITGB1 has a heterodimer form (By similarity).
CC ITGA5:ITGB1 interacts with CCN3 (By similarity). ITGA4:ITGB1 is found
CC in a ternary complex with CX3CR1 and CX3CL1 (By similarity).
CC ITGA5:ITGB1 interacts with FBN1 (By similarity). ITGA5:ITGB1 interacts
CC with IL1B. Interacts with MDK. ITGA4:ITGB1 interacts with MDK; this
CC interaction mediates MDK-induced osteoblast cells migration through PXN
CC phosphorylation. ITGA6:ITGB1 interacts with MDK; this interaction
CC mediates MDK-induced neurite-outgrowth (By similarity). ITGA5:ITGB1
CC interacts with ACE2 (By similarity). Interacts with TMEM182 and LAMB1
CC (By similarity). {ECO:0000250|UniProtKB:P05556,
