Precursor

proteolytically cleaved in late endosomes to yield a soluble form

HOMOLOGY

	intracellular,cytoplasm,organelle,endosome
	intracellular,cytoplasm,organelle,lysosome
text	cleaved into a soluble form found in lysosome lumen
	LAPTM5 and CD1E colocalize in trans-Golgi and late endosomal compartments

basic FUNCTION	involved in the immune response
	helping to expand the repertoire of glycolipidic T cell antigens to optimize antimicrobial immune resposnes
	related to the peptide-presenting MHC class I family
	could be a pot
	participates in the presentation of lipid antigens in dendritic cells

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

forming heterodimer with beta-2-microglobulin

INTERACTION

DNA

RNA

small molecule

protein

interaction of LAPTM5 with CD1E, suggesting that LAPTM5 might influence the role of CD1E in the presentation of lipid antigens

cell & other

REGULATION

Other

mono-ubiquitinated, ubiquitination of CD1E appears to trigger its exit from Golgi compartments and its transport to endosomes

ASSOCIATED DISORDERS

corresponding disease(s)

Susceptibility

Variant & Polymorphism other	one variant of CD1E with a proline at position 194, does not assist PIM(6) presentation to CD1b-restricted specific T cells, homozygous individuals might display an altered immune response to complex glycolipid Ags
