Preparation and Storage

Background: SCAMP3

SCAMP3 (Secretory carrier membrane protein 3) is a 38‑40 kDa member of the SCAMP family of proteins. It is expressed in heart and skeletal muscle, plus fat, and functions in post-Golgi recycling and EGFR internalization pathways. Human SCAMP3 is 347 amino acids (aa) in length. It contains a cytoplasmic N-terminus (aa 1‑170) that shows three NPF repeats (binding sites for EH domain proteins), a heptad repeat of aliphatic aa's, and a potential SH3-binding motif. This is followed by four consecutive transmembrane domains (aa 171‑297) plus a C-terminal cytoplasmic region (aa 298‑347). It appears that phosphorylation of SCAMP3 on Tyr41 is a requisite for its interaction with EGFR. There are three potential splice forms. One shows a deletion of aa 23‑48, while two others show a one and 23 aa substitution for aa 131‑144 and 131‑260, respectively. Over aa 1‑170, human and mouse SCAMP3 are 91% aa identical.
