Enables fusogenic activity and identical protein binding activity. Involved in several processes, including anatomical structure morphogenesis; egg-laying behavior; and nematode pharyngeal muscle development. Located in cell-cell contact zone; cytoplasm; and plasma membrane. Part of EFF-1 complex. Expressed in several structures, including P3.pa; P3.pp; hypodermis; tail spike; and vulval cell.
Predicted to be located in intracellular membrane-bounded organelle. Is an ortholog of human ARL14EP (ARF like GTPase 14 effector protein) and ARL14EPL (ARF like GTPase 14 effector protein like).
Predicted to enable cysteine-type deubiquitinase activity and proteasome binding activity. Predicted to be involved in negative regulation of ERAD pathway. Predicted to be part of proteasome complex. Is an ortholog of human USP14 (ubiquitin specific peptidase 14).
