Predicted to enable signaling receptor complex adaptor activity and ubiquitin-specific protease binding activity. Involved in protein linear deubiquitination; regulation of necroptotic process; and regulation of tumor necrosis factor-mediated signaling pathway. Acts upstream of or within seminiferous tubule development and spermatogenesis. Located in cytoplasm. Is expressed in several structures, including alimentary system; eye; genitourinary system; nervous system; and respiratory system. Orthologous to human SPATA2 (spermatogenesis associated 2).
