Description: Homo sapiens cathepsin L2 (CTSV), transcript variant 1, mRNA. RefSeq Summary (NM_001333): The protein encoded by this gene, a member of the peptidase C1 family, is a lysosomal cysteine proteinase that may play an important role in corneal physiology. This gene is expressed in colorectal and breast carcinomas but not in normal colon, mammary gland, or peritumoral tissues, suggesting a possible role for this gene in tumor processes. Alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jan 2011]. Transcript (Including UTRs) Position: hg19 chr9:99,796,636-99,801,592 Size: 4,957 Total Exon Count: 7 Strand: - Coding Region Position: hg19 chr9:99,796,989-99,799,858 Size: 2,870 Coding Exon Count: 5
ID:CATL2_HUMAN DESCRIPTION: RecName: Full=Cathepsin L2; EC=3.4.22.43; AltName: Full=Cathepsin U; AltName: Full=Cathepsin V; Flags: Precursor; FUNCTION: Cysteine protease. May have an important role in corneal physiology. CATALYTIC ACTIVITY: The recombinant enzyme hydrolyzes proteins (serum albumin, collagen) and synthetic substrates (Z-Phe-Arg- NHMec > Z-Leu-Arg-NHMec > Z-Val-Arg-NHMec). SUBCELLULAR LOCATION: Lysosome (Potential). TISSUE SPECIFICITY: Predominantly expressed in the thymus and testis. Also expressed in corneal epithelium, and to a lesser extent in conjunctival epithelium and skin. SIMILARITY: Belongs to the peptidase C1 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
