Summary: Predicted to enable phosphatidylinositol binding activity. Predicted to be involved in several processes, including establishment of cell polarity; establishment of centrosome localization; and establishment or maintenance of epithelial cell apical/basal polarity. Predicted to be located in cell junction. Predicted to be part of protein-containing complex. Predicted to be active in several cellular components, including adherens junction; apical junction complex; and apical plasma membrane. Is expressed in brain; genitourinary system; nose; and stomach. Orthologous to human PARD3B (par-3 family cell polarity regulator beta). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Par3L is expressed by multipotent stem cells in the terminal end buds of murine mammary glands. Ablation of Par3L resulted in rapid and profound stem cell loss.
Title: The Par3-like polarity protein Par3L is essential for mammary stem cell maintenance.
Atp6ap2/(P)RR interacted with partitioning defective 3 homolog (PAR3) protein, which is known to function in the Par-atypical protein kinase C
Title: Atp6ap2/(pro)renin receptor interacts with Par3 as a cell polarity determinant required for laminar formation during retinal development in mice.

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.
