Rnf31 - ring finger protein 31

Predicted to enable several functions, including linear polyubiquitin binding activity; polyubiquitin modification-dependent protein binding activity; and ubiquitin protein ligase binding activity. Involved in CD40 signaling pathway; positive regulation of I-kappaB kinase/NF-kappaB signaling; and protein ubiquitination. Acts upstream of or within negative regulation of necroptotic process. Located in cytoplasmic side of plasma membrane and cytosol. Part of CD40 receptor complex. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system gland; and sensory organ. Orthologous to human RNF31 (ring finger protein 31).
