Integrin beta-1 is a protein that in humans is encoded by the ITGB1 gene.[1] CD29 is an integrin unit associated with very late antigen receptors. It is known to conjoin with alpha-3 subunit to create α3β1 complex that reacts to such molecules as netrin-1 and reelin.

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. The protein encoded by this gene is a beta subunit. Six alternatively spliced variants have been found for this gene which encode five proteins with alternate carboxy termini.[2]


CD29 has been shown to interact with TSPAN4,[3] CD9,[4][5] Filamin,[6][7] FLNB,[6] CD81,[5][8] CD46,[9] MAP4K4,[10] FHL2,[11] NME1,[12] PKC alpha,[13][14] YWHAB,[15] ITGB1BP1,[16][17] LGALS8[18] and GNB2L1.[13][19] A neutralizing antibody for CD29 is AIIB2.
