Gene

Nkx2-3

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

Functioni

Transcriptional regulator essential for normal development and functions of the small intestine and spleen. Activates directly MADCAM1 expression. Required for homing of lymphocytes in spleen and mucosa-associated lymphoid tissue. May have a role during pharyngeal organogenesis.1 Publication

Expressioni

Tissue specificityi

Expressed in spleen and intestine. Also expressed in salivary gland and tongue.1 Publication

Developmental stagei

Expressed in gut mesenchyme during pre- and postnatal development. Expressed as well in the pharyngeal floor and pouches, and in the oral and branchial arch ectoderm. Expression persisted in the developing thyroid until birth, in mucous forming cells of salivary glands and in odontogenic epithelium of the mandible.

Similar proteinsi

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.
