Gene

Bpifb1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

May play a role in innate immunity in mouth, nose and lungs. Binds bacterial lipopolysaccharide (LPS) and modulates the cellular responses to LPS. May be involved in formation of the left-right axis in the node of the developing embryo.2 Publications

Expressioni

Tissue specificityi

Expressed in tongue, lung, thymus, and stomach. Expressed in epithelia of palate, anterior pharynx, trachea and upper bronchi. Expressed in distal tip of papillae in the anterior third of the tongue and in serous cells of von Ebner glands in the posterior third of the tongue. Expressed in columnar epithelium of the duodenum in embryonic gut at 16.5 dpc.2 Publications

Developmental stagei

Detectable in crown cells of the embryonic node from E7.5. Initial uniform expression develops asymmetrically with a higher level on the left side of the node until expression disappears around E13.5. Expressed in antrum pyloricum of the stomach from E11.5 to E16.5 and in dorsal tongue epithelium from E14.5 to E16.5.1 Publication

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.
