PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	4 laminin A/neurexin/sex hormone-binding (LNS) globular domains separated by
	13 EGF-like motifs within the N terminal short arm allowing the self assembly of chains through interactions of the most terminal globular domain (VI)
	a long arm composed of heptad repeats typical of an cell alpha helical coiled-coil protein
	C-terminal region of beta chains is involved in laminin recognition by integrins and modulates the binding affinities of laminins toward X2-type integrins

SUBCELLULAR LOCALIZATION	extracellular
text	glomeruli, nerve fascicle perineurium, vascular, basement membrane of neuromuscular junction (matrix and synaptic cleft of the neuromuscular junction)

basic FUNCTION	mediating the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components
	playing a role in anchoring as well as differentiation of podocytes foot processes
	basement membrane protein laminin beta2, which is incorporated in specific heterotrimeric laminin isoforms
	essential component of the basement membrane
