ID:NEC1_HUMAN DESCRIPTION: RecName: Full=Neuroendocrine convertase 1; Short=NEC 1; EC=3.4.21.93; AltName: Full=Prohormone convertase 1; AltName: Full=Proprotein convertase 1; Short=PC1; Flags: Precursor; FUNCTION: Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues. Substrates include POMC, renin, enkephalin, dynorphin, somatostatin and insulin. CATALYTIC ACTIVITY: Release of protein hormones, neuropeptides and renin from their precursors, generally by hydrolysis of -Lys- Arg-|- bonds. COFACTOR: Calcium. SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle. Note=Localized in the secretion granules. POLYMORPHISM: Genetic variations in PCSK1 define the body mass index quantitative trait locus 12 (BMIQ12) [MIM:612362]. Variance in body mass index is a susceptibility factor for obesity. DISEASE: Defects in PCSK1 are the cause of proprotein convertase 1 deficiency (PC1 deficiency) [MIM:600955]. PC1 deficiency is characterized by obesity, hypogonadism, hypoadrenalism, reactive hypoglycemia as well as marked small-intestinal absorptive dysfunction It is due to impaired processing of prohormones. SIMILARITY: Belongs to the peptidase S8 family. Furin subfamily.
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.
