4F2 cell-surface antigen heavy chain is a protein that in humans is encoded by the SLC3A2 gene.[1][2]

This gene is a member of the solute carrier family and encodes a cell surface, transmembrane protein with an alpha amylase domain. The protein exists as the heavy chain of a heterodimer, covalently bound through di-sulfide bonds to one of several possible light chains. It associates with integrins and mediates integrin-dependent signaling related to normal cell growth and tumorigenesis. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.[2]



SLC3A2 has been shown to interact with SLC7A7.[3]
