Cathepsin B (P00787)

Uniprot ID P00787
Protein Name Cathepsin B
Gene Name Ctsb
Species Rattus norvegicus (Rat)
Signal peptide(a) Y Secretome P(b)
Function Thiol protease which is believed to participate in intracellular degradation and turnover of proteins (PubMed:1639824). Cleaves matrix extracellular phosphoglycoprotein MEPE (By similarity). Involved in the solubilization of cross-linked TG/thyroglobulin in the thyroid follicle lumen (By similarity). Has also been implicated in tumor invasion and metastasis (By similarity). .

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
