Biological Activity

Description

The PDIA4 protein plays a key role in the chaperone complex, cooperating with various proteins. This dynamic assembly, including DNAJB11, HSP90B1 and others, orchestrates complex cellular processes. PDIA4 Protein, Human (HEK293, His) is the recombinant human-derived PDIA4 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

PDIA4 plays a crucial role as a constituent of a sizable chaperone multiprotein complex, collaborating with DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA6, PPIB, SDF2L1, and UGGT1, with trace amounts of ERP29 present. Notably absent or present in minimal quantities are CALR and CANX. This complex serves as a dynamic assembly of molecular chaperones, orchestrating intricate cellular processes. Additionally, PDIA4 is an integral component of another complex alongside CRELD2, MANF, and MATN3, indicating its versatile engagement in diverse molecular networks. The interplay within these complexes highlights the significance of PDIA4 in maintaining cellular homeostasis and supporting various biological functions.

Verified Bioactivity

Measured by its ability to catalyze the reduction of insulin. The reaction leads to precipitation, which can be measured by absorbance at 650 nm. The specific activity is 0.1727 A650/min/mg.
