Background: DAPP1

DAPP1 (Dual Adaptor for Phosphotyrosine and 3-Phosphoinosidides 1; also Bam32 and PHISH) is a 31-32 kDa member of Ig-superfamily of proteins. It shows restricted expression, being found in mast cells, dendritic cells, and germinal center B cells. With respect to B cells, and upon B cell receptor engagement, PI3-kinase is activated, resulting in the generation of membrane-embedded PI(3,4)P2. This product serves as a ligand for cytosolic DAPP1, resulting in its immobilization at the cell membrane. Here, it is phosphorylated on Tyr139, directly regulating HPK1 (hematopoietic progenitor kinase 1) activity, and indirectly regulation HPK1 downstream targets ERK and JNK. Functionally, DAPP1 plays a role in BCR internalization, antibody isotype switching, antigen processing and presentation, and B cell survival. Human DAPP1 is 280 amino acids (aa) in length. It contains one SH2 domain (aa 35‑129), a utilized phosphorylation site at Tyr139 and a C-terminal PH domain (aa 164‑259). When phosphorylated, the observed MW of DAPP1 may be increased by 2-4 kDa in SDS-PAGE. There are four potential alternative splice variants. Two contain a five and 22 aa substitution for aa 259-280, respectively, while a third possesses a 14 aa substitution for aa 1-229, and a fourth shows deletions of aa 35‑75 and aa 180-200 coupled to a three aa substitution for aa 249-280. Over aa 1-163, human DAPP1 shares 91% aa sequence identity with mouse DAPP1.
