Recombinant Human PILRA Protein, hFc Tag

Molecular Characterization: PILRA (Gln20-Glu195) hFc (Glu99-Ala330) Molecular weight: The protein has a predicted molecular mass of 46.2 kDa after removal of the signal peptide. The apparent molecular mass of PILRA-hFc is approximately 55-70 kDa due to glycosylation.Description: Recombinant Human PILRA Protein with C-terminal human Fc tagCell signaling pathways rely on a dynamic interaction between activating and inhibiting processes. SHP-1-mediated dephosphorylation of protein tyrosine residues is central to the regulation of several cell signaling pathways. Two types of inhibitory receptor superfamily members are immunoreceptor tyrosine-based inhibitory motif (ITIM) -bearing receptors and their non-ITIM-bearing, activating counterparts. Control of cell signaling via SHP-1 is thought to occur through a balance between PILRalpha-mediated inhibition and PILRbeta-mediated activation. These paired immunoglobulin-like receptor genes are located in a tandem head-to-tail orientation on chromosome 7. This particular gene encodes the ITIM-bearing member of the receptor pair, which functions in the inhibitory role. Alternative splicing has been observed at this locus and three variants, each encoding a distinct isoform, are described.
