Cytosolic 5'-nucleotidase 3A

Gene

Nt5c3a

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Nucleotidase which shows specific activity towards cytidine monophosphate (CMP) and 7-methylguanosine monophosphate (m7GMP). CMP seems to be the preferred substrate.By similarity

Expressioni

Tissue specificityi

Isoform 2 is highly expressed in the brain, heart, spleen, kidney and blood. Isoform 2 is expressed (at protein level) in the spleen, skeletal muscle and gastrointestinal epithelia.

Developmental stagei

Isoform 2 is weakly expressed from E7.5 and the expression level steadily increases through gestation. At E9.5 and E10.5 is first detected colocalizing with embryonic blood cells within the region of the septum transversum and within the cardiac chambers and dorsal aorta. At E12.5 expression is found in the ventral neural tube and in the trigeminal ganglia and in the liver and dorsal root ganglia. Expression persists in the liver, dorsal root and trigeminal ganglia at E13.5 and weaker expression becomes apparent in cardiac and skeletal muscle. At E16.5 expression is detected in liver, myocardium, tongue, bronchial epithelium, gastrointestinal epithelium, cartilage and forebrain neuroepithelium.

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.
