Gene: Psap (prosaposin) Mus musculus
Symbol: Psap
Name: prosaposin
Description: Exhibits G protein-coupled receptor binding activity. Involved in several processes, including animal organ development; cornified envelope assembly; and galactosylceramide catabolic process. Localizes to the cytoplasm and extracellular region. Used to study Krabbe disease and metachromatic leukodystrophy. Human ortholog(s) of this gene implicated in atypical Gaucher's disease due to saposin c deficiency and combined saposin deficiency. Is expressed in several structures, including alimentary system; craniocervical region; genitourinary system; hemolymphoid system; and respiratory system. Orthologous to human PSAP (prosaposin).
Type: protein-coding
RefSeq Status: REVIEWED
