Predicted to enable several functions, including ceramide binding activity; microtubule binding activity; and ubiquitin protein ligase binding activity. Involved in autophagy. Acts upstream of or within positive regulation of mucus secretion. Located in autolysosome; axoneme; and membrane. Is expressed in several structures, including central nervous system; heart; limb; peripheral nervous system ganglion; and sensory organ. Orthologous to several human genes including MAP1LC3B (microtubule associated protein 1 light chain 3 beta). [provided by Alliance of Genome Resources, Apr 2022]
