The results suggest that NHERF1 and NHERF2 down-regulated SR-B1 at least in part via the ubiquitin/proteasome pathway.
Title: NHERF1 and NHERF2 regulation of SR-B1 stability via ubiquitination and proteasome degradation.
NHERF2 domain was functionally significant in NHE3 regulation, being necessary for stimulation by lysophosphatidic acid of activity and increased mobility of NHE3
Title: NHERF2 protein mobility rate is determined by a unique C-terminal domain that is also necessary for its regulation of NHE3 protein in OK cells.
data establish NHERF1 and NHERF2 as SR-BI protein binding partners that play a negative role in the regulation of SR-BI expression, selective CE transport, and steroidogenesis.
Title: Regulation of expression and function of scavenger receptor class B, type I (SR-BI) by Na+/H+ exchanger regulatory factors (NHERFs).
The cochlear localization of NHERF scaffolds suggests that they play important roles in the developmental regulation of ion transport, homeostasis, and auditory neurotransmission.
Title: Postnatal developmental expression of the PDZ scaffolds Na+ -H+ exchanger regulatory factors 1 and 2 in the rat cochlea.
NHERF2 selectively restricts downstream coupling of mGluR5 and P2Y1Rs in neurons to G(q)-mediated responses. Differential distribution of NHERF2 in neurons may therefore determine coupling of mGluR5 and P2Y1 receptors to calcium channels.
Title: The scaffold protein NHERF2 determines the coupling of P2Y1 nucleotide and mGluR5 glutamate receptor to different ion channels in neurons.
These findings implicate the GLAST-NHERF1 complex in the regulation of glutamate homeostasis in astrocytes.
Title: Na+-H+ exchanger regulatory factor 1 is a PDZ scaffold for the astroglial glutamate transporter GLAST.
NHERF2 stimulates PDGF-induced proliferation by increasing PI-3-kinase/Akt, MEKindependent ERK, and Src family kinase-mediated signaling pathways
Title: NHERF2 increases platelet-derived growth factor-induced proliferation through PI-3-kinase/Akt-, ERK-, and Src family kinase-dependent pathway.
decreased expression of NHERF1 may be related to the enhanced NHE activity in SHR and that these changes are likely to be genetically determined, whereas the increased NHERF2 expression may be induced as a compensatory mechanism
Title: Expression of the Na+/H+ exchanger regulatory protein family in genetically hypertensive rats.
Since ASIC3 sustained current in nociceptor excitability, it is likely that NHERF-1 participates in channel functions associated with nociception and mechanosensation.

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.
