Function

This gene encodes a member of the GRB2/Sem5/Drk family. This member is an adaptor-like protein involved in leukocyte-specific protein-tyrosine kinase signaling. Like its related family member, GRB2-related adaptor protein (GRAP), this protein contains an SH2 domain flanked by two SH3 domains. This protein interacts with other proteins, such as GRB2-associated binding protein 1 (GAB1) and the SLP-76 leukocyte protein (LCP2), through its SH3 domains. Transcript variants utilizing alternative polyA sites exist.^[7]

Interactions

GRAP2 has been shown to interact with:

• CCNDBP1,^[8]
• CD28,^[9]
• Linker of activated T cells,^[6][10]
• Lymphocyte cytosolic protein 2^{[6][9][11][10]}
• MAP4K1,^[12] and
• STAMBP.^[6][11]
