Biological Activity

Description

CALB1 Protein, Human (His, Strep) is the recombinant human-derived CALB1, expressed by E. coli, with Strep, His labeled tag.

Background

Calbindin is a calcium-binding protein that primarily buffers cytosolic calcium ions. It may regulate calcium signaling pathways by stimulating a membrane Ca2+-ATPase and a 3',5'-cyclic nucleotide phosphodiesterase.
