These findings indicate that VEGF decreases P-glycoprotein activity via activation of flk-1 and Src, and suggest Src-mediated phosphorylation of caveolin-1 may play a role in downregulation of P-glycoprotein activity.
Title: Rapid, reversible modulation of blood-brain barrier P-glycoprotein transport activity by vascular endothelial growth factor.
Transcription of rat hepatic Mrp2 mRNA is initiated at multiple sites and contains potential upstream open reading frames (uORFs) in the 5' untranslated region (UTR) starting at -213, -149 and -109 nucleotides.
Title: Translational regulation of rat multidrug resistance-associated protein 2 expression is mediated by upstream open reading frames in the 5' untranslated region.
HAX-1 binds bile salt export protein (BSEP), cortactin, MDR1, and MDR2. HAX-1 and cortactin regulate BSEP abundance in the apical membrane of cells.

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.
