CALHM1 controls cytosolic Ca2+ permeability and cytosolic Ca2+ concentration. It controls amyloid precursor protein (APP) proteolysis and aggregated amyloid-beta (Abeta) peptides levels in a Ca2+ dependent manner. However, no association between CALHM1 and Alzheimer?s risk is unclear. Member of the FAM26 family of proteins. CALHM1 is predominantly expressed in the adult brain. It has also been detected in retinoic acid-differentiated SH-SY5Y cells. Also colocalizes with HSPA5 at the endoplasmic reticulum.


Synthetic peptide derived from human CALHM1 protein.

Positive Control

Human hepatocellular carcinoma


Provided as solution in phosphate buffered saline with 0.08% sodium azide
