Generic protein structure example


Ras-interacting protein 1 (Rain), is a protein that in humans is encoded by the RASIP1 gene.[1]

Function

  • It is required for the proper formation of vascular structures that develop via both vasculogenesis and angiogenesis.[2]
  • Acts as a critical and vascular-specific regulator of GTPase signaling, cell architecture, and adhesion, which is essential for endothelial cell morphogenesis and blood vessel tubulogenesis.[3][4][5]
  • Regulates the activity of Rho GTPases in part by recruiting ARHGAP29 and suppressing RhoA signaling and dampening ROCK and MYH9 activities in endothelial cells.[6][7]

Clinical significance

A recent genome-wide association study (GWAS) has found that genetic variations in RASIP1 are associated with late-onset sporadic Alzheimer’s disease (LOAD). However, it's unknown how RASIP1 mutation contributes to disease.[8]
