View in BioMuta


ITGB1 is a beta subunit of the heterodimeric integrin protein. Integrins are ubiquitously expressed adhesion molecules composed of alpha and beta subunits. In mammals, 18 alpha and 8 beta subunits have been identified. 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. Several protein isoforms have been identifed, arising from alternatively spliced transcript variants.
