| Abstract |
Integrin-associated protein (IAP, CD47) is a plasma membrane receptor for thrombospondins and signal regulatory proteins (SIRPs) that has an essential role in host defense through its association with integrins. The IAP gene encodes alternatively spliced carboxyterminal cytoplasmic tails that have no previously described function. IAP cytoplasmic tails can bind two related proteins that mediate interaction between IAP and vimentin-containing intermediate filaments, named proteins linking IAP with cytoskeleton (PLICs). Integrins interact with PLICs indirectly, through IAP. Transfection of PLICs induces redistribution of vimentin and cell spreading in IAP-expressing cells. This novel connection between plasma membrane and cytoskeleton is likely to be significant in many adhesion-dependent cell functions. |
