Epididymis secretory sperm binding protein Li 130P
HEL S 130P
Lysosomal aspartyl peptidase
Lysosomal aspartyl protease
FunctionAcid protease active in intracellular protein breakdown. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease.
Tissue specificityExpressed in the aorta extrcellular space (at protein level).
Involvement in diseaseCeroid lipofuscinosis, neuronal, 10
Sequence similaritiesBelongs to the peptidase A1 family. Contains 1 peptidase A1 domain.
Post-translational modificationsN- and O-glycosylated.
Cellular localizationLysosome. Melanosome. Secreted, extracellular space. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. In aortic samples, detected as an extracellular protein loosely bound to the matrix (PubMed:20551380).
