Description

The MAb XML1Y1 recognizes CD304 (Neuropilin-1), a type 1 transmembrane glycoprotein present on the surface of multiple cell types, including: regulatory T cells (Tregs), NKT cells, DC, certain types of stem cells, neurons, endothelial cells, and some neoplastic cells. Neuropilin-1, in complex with plexins, serves as a co-receptor for type 3 semaphorins in growing neurons. It is also involved in the process of angiogenesis being a part of a functional receptor for VEGF in endothelial cells. In mouse Neuropilin-1 is expressed on thymus-derived natural Tregs but not peripherally induced Treg cells. In addition, transient expression on recently activated non-regulatory T cells has been observed. Neuropilin-1 has been used as a marker of recent thymic emigrants in the mouse iNKT cell population. It has been shown that Neuropilin-1 forms a complex with TGF beta receptors, activating TGF beta latent form (LAP-TGF beta 1) and augmenting canonic Smad2/3 signaling. This XML1Y1 antibody recognizes neuropilin-1 isoforms 1 and 2.

Neuropilin 1 is a 923 amino acid containing membrane bound coreceptor to a tyrosine kinase receptor belonging to the neuropilin family with two CUB domains, two F5/8 type C domains and a MAM domain. Neuropilin 1 forms a heterodimer with NRP2 (Neuropilin 2) and is known to bind to plexin (PLXNB1) to form semaphorin receptors. Expressed mostly in the nervous system this receptor is implicated in a wide range of functions including in the development of the cardiovascular system, angiogenesis, repulsive axon guidance, formation of certain neuronal circuits, cell survival, control of neuronal migration and organogenesis outside the nervous system. This semaphorin receptor functions as receptors for both the semaphorins and vascular endothelial growth factor and is also a regulator of VEGF-induced angiogenesis. Neuropilin 1 may be involved in aggressive advanced prostate carcinoma and in the progression of breast cancer.
