Purity ~90% (SDS-PAGE). NXPH1 is a member of the neurexophilin family and encodes a secreted protein with a variable N-terminal domain, a highly conserved, N-glycosylated central domain, a short linker region, and a cysteine-rich C-terminal domain. This protein forms a very tight complex with alpha neurexins, a group of proteins that promote adhesion between dendrites and axons. Source: Recombinant corresponding to aa22-271 from human NXPH1 protein, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~31kD (273aa) Applications: Suitable for use in SDS-PAGE.
