PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	an Ig extracellular domain
	a cytoplasmic tail with the immunoreceptor tyrosine based activation motif (ITAM), isoform TAC12, 12kDa
	three NFAT binding motifs (for NFATC1, NFATC2 and NFKB2)
	highly evolutionarily conserved CXXC motif
	a short extracellular stalk connecting its Ig-like domains to its transmembrane regions

conjugated

GlycoP

HOMOLOGY

interspecies	ortholog to murine Cd3g

FAMILY

immunoglobulin superfamily

CATEGORY

antigen

SUBCELLULAR LOCALIZATION	plasma membrane
text	type I membrane protein

basic FUNCTION	mediating signal transduction
	the stalks of the CD3G, CD3E, CD3D, CD247 may be critical in transmitting part of the activation signal directly through the membrane
	CD3G and CD3D evolved from a common precursor gene to optimize peptide/MHC-triggered alphabeta TCR activation
	important role of the CD3G diL motif in T-cell development most probably mediated by its fine-tuning of pre-TCR and TCR expression, down-regulation and signaling
