Also known as: UP3a; Upk3; UPIII; 1110017C07Rik
Summary: Acts upstream of or within several processes, including potassium ion homeostasis; urea transport; and urinary bladder development. Located in apical plasma membrane. Is active in apical plasma membrane urothelial plaque. Is expressed in several structures, including alimentary system; genitourinary system; lung; notochord; and olfactory epithelium. Used to study vesicoureteral reflux. Orthologous to human UPK3A (uroplakin 3A). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

U-CCs (Uroplakin3a expressing cells )proliferate and generate CCs and ciliated cells in uninjured airways long-term and, like v-CCs, after Nap. U-CCs have a higher propensity to generate ciliated cells than non-U-CCs

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
