C-terminal domain of cysteine and histidine-rich protein 1 and similar proteins
Cysteine and histidine-rich protein 1 (CYHR1) was first identified as an interaction partner of murine galectin-3. Its biological function is still unknown, but it has been shown to be a prognostic marker for esophageal squamous cell carcinoma and a biomarker in hemodialysis patients for the response to erythropoietin. CYHR1 contains an N-terminal C3HC4-type RING-HC finger. This model represents the conserved C-terminal domain of unknown function.
