Phosphoprotein Associated with Glycosphingolipid-Enriched Microdomains

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Phosphoprotein associated with glycosphingolipid-enriched microdomains 1 (423 aa, ~47 kDa) is encoded by the human PAG1 gene. This protein is involved in the regulation of T-cell antigen receptor (TCR)-mediated and high affinity immunoglobulin epsilon receptor (FCER1)-mediated signaling in T-cells and mast cells, respectively.

**Synonyms:** - Csk-Binding Protein - PAG - Phosphoprotein Associated with GEMs - Transmembrane Adapter Protein PAG - Transmembrane Adaptor Protein PAG - Transmembrane Phosphoprotein Cbp
