Enables several functions, including identical protein binding activity; phosphatase binding activity; and phosphatase regulator activity. Predicted to be involved in regulation of GTPase activity. Predicted to act upstream of or within autophagy. Located in vacuolar membrane. Is expressed in several structures, including central nervous system; genitourinary system; gut; heart; and sciatic nerve. Used to study Charcot-Marie-Tooth disease type 4B2. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 4B2. Orthologous to human SBF2 (SET binding factor 2). [provided by Alliance of Genome Resources, Apr 2022]
