About GRAP2

Cytogenetic location: 22q13.1 Genomic coordinates (GRCh38): 22:39,893,820-39,973,721 (from NCBI)

This gene has 7 transcripts (splice variants), 260 orthologues and 9 paralogues. Broad expression in lymph node (RPKM 6.7), spleen (RPKM 4.1) and 17 other tissues.

Summary

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. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Apr 2014]
