Plexin-C1 also known as Virus-encoded semaphorin protein receptor, is a ∼210 kDa type I transmembrane receptor that regulates cytoskeletal remodeling and adhesion in human melanocytes.
It belongs to the family of Plexin receptors, these are type I transmembrane proteins (A–D) that share a highly conserved cytoplasmic domain and an intracellular region containing an intrinsic Ras-GTPase activating (GAP) domain. Plexin receptors bind semaphorins: a class of secreted and membrane proteins 1. The natural ligand of Plexin C1 is Semaphorin -7A (#ASR-077).
Plexin-C1 is highly expressed in melanocytes, neurons, neutrophils, dendritic cells and pre-osteoblasts and it has a complex effect on migration of melanocytes and melanoma, that depends on the phase of progression of this type of cancer 2,3. It also has additional roles in the partitioning of paraventricular and supraoptic neurons in the hypothalamus, in the development of inflamation and in inhibition of neutrophils phagocytosis 3,4.
