Predicted to enable scaffold protein binding activity. Acts upstream of or within extrinsic apoptotic signaling pathway; hepatocyte apoptotic process; and tumor necrosis factor-mediated signaling pathway. Located in cell periphery and keratin filament. Is expressed in several structures, including alimentary system; brain; early conceptus; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in liver cirrhosis. Orthologous to human KRT18 (keratin 18). [provided by Alliance of Genome Resources, Apr 2022]
