Cold-inducible RNA-binding protein

Gene

cirbp

Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Cold-inducible mRNA binding protein. Acts cooperatively with elavl1/elrA to stabilize AU-rich element (ARE)-containing mRNAs by binding to themm and inhibiting their deadenylation. Essential for embryonic gastrulation and neural development, acting to maintain the expression of a set of adhesion molecules, and cell movement during embryogenesis. Required for pronephros development (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
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.
