Alternate Names for Reg1A/B Antibody [Unconjugated]
Reg1A (Regenerating gene IA/ alpha ; also REG, ICRF, PSPS, PTP and Lithostathine-1 alpha ) is a secreted, variably glycosylated 15-22 kDa type I member of the REG gene family of proteins. It is induced in proliferating cell types such as colonic epithelium, islet beta -cells, and multiple tumor types, and is constitutively expressed by pancreatic acinar cells. Thus, Reg1A is found both in blood (ng/mL quantities) and pancreatic secretions. It would appear that Reg1A plays a role in blocking apoptosis, and is upregulated by both IL-22 and IL-6. Human Reg1A is synthesized as a 166 amino acid (aa) precursor. It contains a 22 aa signal sequence plus a 144 aa mature region that is characterized by the presence of three intrachain disulfide bonds, one C-type lectin domain (aa 34-164), and a utilized N-terminal O-linked glycosylation site (Thr27). Variablility in the glycosylation pattern, plus proteolytic cleavage after Arg11 generates Reg1A isoforms in the 15-22 kDa range. There is one potential isoform variant that shows an alternative start site at Met9. Mature (aa 23-166) human Reg1A shares 76% and 69% aa sequence identity with mouse and rat Reg1A, respectively.
Reg1B, also known as secretory pancreatic stone protein 2 and lithostathine 1 beta, is a type I subclass member of the Reg family, which comprises secreted proteins with a C-type lectin domain. Reg1B is highly related to Reg1A, a protein that is implicated in islet cell regeneration and diabetogenesis.
