Recombinant Human AHSG protein, His-tagged

• Cat.No.: AHSG-7710H
• Product Overview: Recombinant Human AHSG (Ala19-Val367) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: Alpha-2-HS-glycoprotein (AHSG) is also known as Alpha-2-Z-globulin, Ba-alpha-2-glycoprotein, Fetuin-A (FETUA), is a glycoprotein that is composed of two subunits, the A and B chains, belongs to the cystatin family of proteases inhibitors and the fetuin class of plasma binding proteins. AHSG/Fetuin A is highly expressed in embryonic cells and adult hepatocytes, and is expressed to a lesser extent in monocytes/macrophages. Fetuins are carrier proteins like albumin. Fetuin-A/AHSG forms soluble complexes with calcium and phosphate and thus is a carrier of otherwise insoluble calcium phosphate. Thus AHSG/Fetuin A is a potent inhibitor of pathological calcification. Fetuin A/FETUA promotes phagocytosis of apoptotic cells and plays a role in bone development, calcium homeostasis and insulin sensitivity. Mice deficient in Fetuin-A show systemic calcification of soft tissues.
