Pref-1/DLK1/FA1 Antibody (211309) [Allophycocyanin]

This product is produced by and ships from R&D Systems, Inc., a Bio-Techne brand.

Pref-1 (Preadipocyte Factor 1), also known as DLK1 and FA1, is a 58-65 kDa member of the Notch/Serrata/Delta family of proteins.  It is expressed in prechondrocytes and preadipocytes and appears to block progenitor cell differentiation into mature cell lineages.  Mature human Pref-1 is a 360 amino acid (aa) type I transmembrane N- and O-linked glycoprotein.  It contains a 280 aa extracellular region (aa 24-303), a 24 aa transmembrane segment (aa 304-327), and a 56 aa cytoplasmic domain (aa 328-383).  The extracellular region contains six EGF-like domains, and undergoes proteolytic cleavage to generate a bioactive 50 kDa fragment, plus three 25-31 kDa fragments that show no activity.  There are multiple potential splice variants.  One shows a deletion of aa 229-301, a second possesses a six aa substitution for aa 1-52, a third shows a deletion of aa 210-277, while a fourth contains a six aa substitution for aa 207-383.  Over aa 24-297, human Pref-1 shares 82% aa identity with mouse Pref-1.
