heavy chain constant region-1

Ig constant chain domains & a single extracellular domain of MHC chains are related. These homologous domains are about 100 amino acid residues with a conserved intradomain disulfide. The constant region of immunoglobulins determines the mechanism used to destroy antigen.

General

immunoglobulin constant region; fragment crystallizable region (Fc)

Properties

MOTIF: cysteine residue {CH1.SITE1} MODIFICATION: cysteine residue {CH1.SITE2} cysteine residue {CH1.SITE2} MODIFICATION: cysteine residue {CH1.SITE1}
