Title: Association of variants in SH2B1 and RABEP1 with worsening of low-density lipoprotein and glucose parameters in patients treated with psychotropic drugs.
The results contradict the model of feedback activation of Rab5 and instead indicate that Rbpt5 is recruited by both Rabex5 recognizing ubiquitylated cargo and by Rab4 to activate Rab5 in a feed-forward manner.
Title: Rabaptin5 is recruited to endosomes by Rab4 and Rabex5 to regulate endosome maturation.
ITSN2L interacts with RABEP1 and stimulates its degradation in regulation of endocytosis.

The pleckstrin homology domain (PH) of PLD1 itself promotes degradation of HIF-1alpha, then accelerates EGFR endocytosis via upregulation of rabaptin-5 and suppresses tumor progression.

Title: Global identification of miR-373-regulated genes in breast cancer by quantitative proteomics.
The authors determined that increased listeriolysin O-independent dissolution of vacuoles during RABEP1 knockdown required the Listeria monocytogenes broad-range phospholipase C (PC-PLC).

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.

Description

Transcript Variant: This variant (4) lacks several 3' exons but contains an alternate 3' terminal exon, and it thus differs in its 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (4) has a distinct C-terminus and is significantly shorter than isoform 1.
