GeneCards Summary for IGHA2 Gene

IGHA2 (Immunoglobulin Heavy Constant Alpha 2 (A2m Marker)) is a Protein Coding gene. Among its related pathways are Vesicle-mediated transport and Cell surface interactions at the vascular wall. GO annotations related to this gene include antigen binding and immunoglobulin receptor binding. An important paralog of this gene is IGHA1.

UniProtKB/Swiss-Prot for IGHA2 Gene

  • Ig alpha is the major immunoglobulin class in body secretions. It may serve both to defend against local infection and to prevent access of foreign antigens to the general immunologic system.
