Background
Glycoprotein A33 (GPA33) is also known as Cell surface A33 antigen, is a single-pass type I membrane protein which is expressed in normal gastrointestinal epithelium and in 95% of colon cancers. GPA33 The predicted mature protein has a 213-amino acid extracellular region, a single transmembrane domain, and a 62-amino acid intracellular tail. The sequence of the extracellular region contains 1 Ig-like C2-type (immunoglobulin-like) domain and 1 Ig-like V-type (immunoglobulin-like) domain characteristic of the CD2 subgroup of the immunoglobulin (Ig) superfamily, which contains. GPA33 may play a role in cell-cell recognition and signaling.
Description
Recombinant Human GPA33/A33 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Ile22-Val235.
Target
GPA33/A33
Species
Human
Gene/Protein ID
Q99795-1
Exact Sequence
Ile22-Val235
Molecular Weight
The protein has a predicted MW of 26.5 kDa. Due to glycosylation, the protein migrates to 28-40 kDa based on the Tris-Bis PAGE result.
