Enables cystathionine beta-synthase activity; cysteine synthase activity; and pyridoxal phosphate binding activity. Involved in sulfur compound biosynthetic process. Located in cytoplasm. Expressed in pharyngeal muscle cell. Human ortholog(s) of this gene implicated in several diseases, including homocystinuria; hyperhomocysteinemia; and neural tube defect. Is an ortholog of human CBS (cystathionine beta-synthase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
