E. coli-derived recombinant human protein (amino acids R42-E454) was used as the immunogen for the SH2D4A antibody.
SH2 domain-containing protein 4A, also called Protein phosphatase 1 regulatory subunit 38 (PPP1R38) is a protein that in humans is encoded by the SH2D4A gene. Using exon trapping and exon linking at chromosome 8p22 cloned SH2D4A, which they called SH2A.
