Function

Regulates granule biogenesis in endocrine cells by up-regulating the transcription of protease nexin 1 (SERPINE2) via a cAMP-PKA-SP1 pathway. This leads to inhibition of granule protein degradation in the Golgi complex which in turn promotes granule formation.

Biological Context

Subcellular Location: Cytoplasmic vesicle, secretory vesicle; Cytoplasmic vesicle, secretory vesicle, neuronal dense core vesicle; Secreted
Tissue Specificity: Found in the brain

Product Specifications

Recombinant Human Chromogranin-A (CHGA) is a recombinant protein from Homo sapiens (Human), expressed in Yeast, covering amino acids 19-457aa, with N-terminal 6xHis-tagged tag, molecular weight 50.9kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.
