Predicted to enable potassium channel regulator activity. Involved in positive regulation of potassium ion transport and positive regulation of protein localization to plasma membrane. Located in cell surface and neuronal cell body. Part of voltage-gated potassium channel complex. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis; autosomal dominant non-syndromic intellectual disability 33; and spinal muscular atrophy. Orthologous to human DPP6 (dipeptidyl peptidase like 6). [provided by Alliance of Genome Resources, Apr 2022]
