| Background Information | Integrin beta 1, also known as CD29, is a 130 kDa transmembrane glycoprotein that forms noncovalent complexes with various Integrin alpha subunits (including alpha 1, alpha 2, alpha 3, alpha 4, alpha 5, and alpha 6) to form the functional receptors that bind to specific extracellular matrix proteins. Integrin receptors are involved in the regulation of a variety of important biological functions, including embryonic development, wound repair, hemostasis, and prevention of programmed cell death. They are also implicated in abnormal pathological states such as tumor directed angiogenesis, tumor cell growth, and metastasis. These heterodimeric receptors bridge the cytoplasmic actin cytoskeleton with proteins present in the extracellular matrix and/or on adjacent cells. Interactions between integrins and the extracellular matrix lead to activation of signal transduction pathways and regulation of gene expression. |

| Application Notes | Immunoprecipitation: A representative lot of this antibody clone was used in immunoprecipitation. Immunohistochemistry: A representative lot of this antibody clone was used in immunohistochemistry (acetone fixation, no paraffin embedding). ELISA: A representative lot of this antibody was used in ELISA. Immunocytochemistry: A representative lot of this antibody clone was used in immunocytochemistry (paraformaldehyde fixation at less than 4%). Functional Activity Assay: A representative lot of this antibody clone was used in cell attachment assay of SV-HFO cells with a characteristic spread morphology. In the presence of function-blocking mAbs to β1 integrin (P5D2), the cells attached but no longer spread, and displayed a rounded morphology with many cytoplasmic projections (Iba, K. et al., 2000). |

| Entrez Gene Summary | Integrins are heterodimeric proteins made up of alpha and beta subunits. At least 18 alpha and 8 beta subunits have been described in mammals. Integrin family members are membrane receptors involved in cell adhesion and recognition in a variety of processes including embryogenesis, hemostasis, tissue repair, immune response and metastatic diffusion of tumor cells. This gene encodes a beta subunit. Multiple alternatively spliced transcript variants which encode different protein isoforms have been found for this gene. |

| UniProt Summary | FUNCTION: SwissProt: P05556 # Integrins alpha-1/beta-1, alpha-2/beta-1, alpha-10/beta- 1 and alpha-11/beta-1 are receptors for collagen. Integrins alpha- 1/beta-1 and alpha-2/beta-2 recognize the proline-hydroxylated sequence G-F-P-G-E-R in collagen. Integrins alpha-2/beta-1, alpha- 3/beta-1, alpha-4/beta-1, alpha-5/beta-1, alpha-8/beta-1, alpha- 10/beta-1, alpha-11/beta-1 and alpha-V/beta-1 are receptors for fibronectin. Alpha-4/beta-1 recognizes one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. Integrin alpha-5/beta-1 is a receptor for fibrinogen. Integrin alpha-1/beta-1, alpha-2/beta-1, alpha-6/beta-1 and alpha-7/beta-1 are receptors for lamimin. Integrin alpha-4/beta-1 is a receptor for VCAM1. It recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-9/beta-1 is a receptor for VCAM1, cytotactin and osteopontin. It recognizes the sequence A-E-I-D-G-I-E-L in cytotactin. Integrin alpha-3/beta-1 is a receptor for epiligrin, thrombospondin and CSPG4. Alpha-3/beta-1 may mediate with LGALS3 the stimulation by CSPG4 of endothelial cells migration. Integrin alpha-V/beta-1 is a receptor for vitronectin. Beta-1 integrins recognize the sequence R-G-D in a wide array of ligands. Isoform beta-1B interferes with isoform beta-1A resulting in a dominant negative effect on cell adhesion and migration (in vitro). In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposis sarcoma lesions. SIZE: 798 amino acids; 88465 Da SUBUNIT: Heterodimer of an alpha and a beta subunit. Beta-1 associates with either alpha-1, alpha-2, alpha-3, alpha-4, alpha- 5, alpha-6, alpha-7, alpha-8, alpha-9, alpha-10, alpha-11 or alpha-V. Interacts with FLNA. Binds LGALS3BP and ITGB1BP3, when associated with alpha-7, but not with alpha-5 (By similarity). Interacts with FLNB and RANBP9. Isoform Beta-1D interacts with ACE2. Isoform Beta-1A interacts with the C-terminal region of FLNC. Interacts with HIV-1 Tat. SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein. Melanosome. Note=Isoform beta-1B does not localize to focal adhesions. Highly enriched in stage I melanosomes. TISSUE SPECIFICITY: Isoform beta-1A is widely expressed, other isoforms are generally coexpressed with a more restricted distribution. Isoform beta-1B is expressed in skin, liver, skeletal muscle, cardiac muscle, placenta, umbelical vein endothelial cells, neuroblastoma cells, lymphoma cells, hepatoma cells and astrocytoma cells. Isoform beta-1C and isoform beta-1C-2 are expressed in muscle, kidney, liver, placenta, cervical epithelium, umbilical vein endothelial cells, fibroblast cells, embryonal kidney cells, platelets and several blood cell lines. Isoform beta-C-2, rather than isoform beta-1C, is selectively expressed in primary T-cells. Isoform beta-1C is expressed in nonproliferating and differentiated prostate gland epithelial cells. Isoform beta-1D is expressed specifically in striated muscle (skeletal and cardiac muscle). SIMILARITY: SwissProt: P05556 ## Belongs to the integrin beta chain family. & Contains 1 VWFA domain. |
