Unlocking INHBE/Activin E: A Key Target in Metabolic Health
What is INHBE/Activin E?
Activin E (beta E/beta E), a pivotal member of the transforming growth factor-β (TGF-β) superfamily, is encoded by the INHBE gene and is predominantly expressed in the liver. It functions as a dimeric protein (~23 kDa), composed of two βE subunits linked by disulfide bonds (Figure 1). Following proteolytic cleavage of its precursor, the mature secreted form circulates in the bloodstream to exert effects on target tissues.

INHBE/Activin E: A Promising Therapeutic Target for Obesity
Research indicates that elevated INHBE gene expression increases Activin E protein levels, which in turn promotes hepatic adiposity, insulin resistance, and metabolic dysfunction-associated fatty liver disease (MAFLD). This process is mediated through the INHBE–Activin E–ALK7 signaling pathway (Figure 2).
INHBE stands out as a compelling target for treating obesity and related metabolic disorders. Its distinct advantage lies in the potential for selective reduction of adipose tissue—particularly visceral fat—while preserving lean muscle mass, a mechanistic profile that differentiates it from conventional weight-loss therapies.

Why Choose ACROBiosystems for INHBE/Activin E Detection?
Why Choose ACROBiosystems for INHBE/Activin E Detection?
The ACRO Human Activin E Dimer ELISA Kit (Cat. No.CEA-B247) is specifically designed to detect the biologically dimeric form of Activin E (beta E/beta E), providing accurate and relevant physiological insights (Figure 3). Unlike other commercial kits that may detect non-dimeric isoforms, our assay ensures target specificity and reliability (Table 1).
The kit is validated for use with human samples, humanized mouse models, and non human primate (NHP) specimens, supporting translational and preclinical research.
