What's a GeneRIF?

The dephosphorylation of CPB1 induced beta-cell proliferation. We thus surmise that the altered PTM of CPB1 is associated with pancreatic regeneration.
Title: Phosphorylation of carboxypeptidase B1 protein regulates β-cell proliferation.
Mutants C383G, C383A had higher k(cat)/K(m) values which indicated increased catalytic abilities. And both had higher thermal stability.

optimum of procarboxypeptidase B activity was achieved at pH 7-9

Distinct bradykinin-processing pathways operate in the perfusates of rat mesenteric/coronary beds, with a substantial participation of a des-Arg(9)-BK-forming enzyme identical to pancreatic CPB.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
