Zinc metalloproteinase nas-37

Gene

nas-37

Organism
Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Metalloprotease that plays an essential role in molting, a process during larval stages in which a new cuticle is formed and the old cuticle is shed. Required during ecdysis, the opening of the cuticle to allow the worm to escape.2 Publications

Catalytic activityi

Hydrolysis of peptide bonds in substrates containing five or more amino acids, preferentially with Ala in P1', and Pro in P2'.

Expressioni

Tissue specificityi

Expressed in hypodermal cells. Not expressed in the seam cells in L1 to L3 larvae, but it is present in seam cells of L4 larvae. Also expressed in attachment points of the cuticle at the anterior end of larvae, in the arcade cells in the mouth, the anterior pharynx, the amphid socket cells, and in the rectal epithelial cells at the posterior end of the larvae (at protein level).2 Publications

Developmental stagei

Present in hypodermal cells of the anterior cuticle 4 hours before each molt and is shed in the cuticle after ecdysis.

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
