• Cat.No.: GPA33-244HAF647
• Product Overview: Alexa Fluor 647 conjugated recombinant human GPA33 (Ile22-Val235) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: His
• ProteinLength: Ile22-Val235
• Description: 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.
