SH2D1B - SH2 domain containing 1B
Entrez Gene Name: SH2 domain containing 1B
Synonyms: EAT-2A, EAT2, RGD1563935, SH2D1B, Sh2d1b1

Gene Summary

  • Human (117157): By binding phosphotyrosines through its free SRC (MIM 190090) homology-2 (SH2) domain, EAT2 regulates signal transduction through receptors expressed on the surface of antigen-presenting cells (Morra et al., 2001 [PubMed 11689425]).[supplied by OMIM]
