Negatively regulates myogenesis and skeletal muscle regeneration via its association with ITGB1 (By similarity). Modulates ITGB1 activation by decreasing ITGB1-LAMB1 interaction and inhibiting ITGB1-mediated intracellular signaling during myogenesis (By similarity). Interacts with ITGB1. Belongs to the TMEM182 family. Extended N-terminus. Extended N-terminus.
