What's a GeneRIF?

the VAP-interacting membrane-associated phosphatidylinositol (PtdIns) transfer proteins PYK2 N-terminal domain-interacting receptor 2 (Nir2) and Nir3 specifically associate with Kv2.1 complexes.
Title: Neuronal ER-plasma membrane junctions organized by Kv2-VAP pairing recruit Nir proteins and affect phosphoinositide homeostasis.
Pitpnm1 null mice showed no hearing defects.
Title: Pitpnm1 is expressed in hair cells during development but is not required for hearing.
results suggest that Nir2 not only enhances EMT in vitro and breast cancer metastasis in animal models, but also contributes to breast cancer progression in human patients.
Title: The lipid-transfer protein Nir2 enhances epithelial-mesenchymal transition and facilitates breast cancer metastasis.
RdgB homologs play a preemptive role in excluding endogenous and exogenous modified purine deoxyribonucleoside triphosphates (dTNPs) from incorporation into DNA.

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.

NR_075078.2 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (2) includes an alternate 5' exon structure compared to variant 1. This variant is represented as non-coding due to the presence of an upstream ORF that is predicted to interfere with translation of the longest ORF; translation of the upstream ORF renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
