Soluble Resistance-related Calcium-binding protein (SRI)

Target
SRI
Molecular classification
Penta-EF-hand calcium-binding protein
01

Overview

Sorcin is a calcium-binding protein involved in regulating intracellular calcium homeostasis. It interacts with multiple calcium channels and transporters, impacting processes such as excitation-contraction coupling and apoptosis. It is highly expressed in some cancers and contributes to multidrug resistance.

Other names
Sorcin
02

Mechanism of action

Direct inhibition or downregulation via RNA interference or small molecules aimed at restoring chemosensitivity or inducing apoptosis selectively within resistant tumor cells.
