	intracellular,nucleus
text	single-pass type I membrane protein

basic FUNCTION	cell surface adhesion receptor mediating cell-adhesion to extra cellular matrix or to other cells, through hetero dimerization and connecting to the cytoskeleton and various signaling molecules within cells
	mediating cell-extracellular matrix interactions also involved in the fertilization and embryonic development
	distinct roles of ITGA6 and ITGA4 in homing of fetal liver hematopoietic stem and progenitor cells
	major role in the proangiogenic properties of endothelial colony-forming cells (ECFCs)
	regulates signaling pathways in a variety of cellular activities
	cell-surface protein, having novel and dynamic roles in regulating the differentiation potential of mesenchymal stem cells and maintaining pluripotency

CELLULAR PROCESS

cell communication

PATHWAY

metabolism

signaling

a component	constituent of VLA-6 receptor
	dimerizing with ITGB1 (laminin receptor) or ITGB4 (constituent of hemidesmosome)
