Receptor for kinesin thus involved in kinesin-driven vesicle motility. Accumulates in integrin-based adhesion complexes (IAC) upon integrin aggregation by fibronectin. Parallel homodimers formed between the membrane-bound and the cytosolic form, and also between 2 cytosolic forms. Vesicle membrane protein anchored to the endoplasmic reticulum. Additional isoforms seem to exist. High levels in peripheral blood lymphocytes, testis and ovary, lower levels in spleen, thymus, prostate, small intestine and colon. Belongs to the kinectin family. Contaminating sequence. Potential poly-A sequence. Extended N-terminus.
