Enables triose-phosphate isomerase activity. Involved in glyceraldehyde-3-phosphate metabolic process. Acts upstream of or within glucose metabolic process. Predicted to be located in nucleus. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study triosephosphate isomerase deficiency. Human ortholog(s) of this gene implicated in carbohydrate metabolic disorder and triosephosphate isomerase deficiency. Orthologous to human TPI1 (triosephosphate isomerase 1). [provided by Alliance of Genome Resources, Apr 2022]
