Increased expression of epimorphin in a peritoneal fibrosis mouse model.
Title: Increased expression of epimorphin in a peritoneal fibrosis mouse model.
he patient showed azoospermia, relatively small testes, and a mildly elevated follicle stimulating hormone level, but no additional clinical features. Testicular histology of the patient showed universal maturation arrest and multinucleated spermatocytes, which have also been observed in mice lacking Stx2. PCR-based cDNA screening revealed wildtype STX2 expression in various tissues including the testis
Title: STX2 is a causative gene for nonobstructive azoospermia.
Syn-2 knockout mice exhibited paradoxical superior glucose homeostasis resulting from an enhanced insulin secretion. The increase in insulin exocytosis was attributed mainly to an enhanced recruitment of the larger pool of newcomer secretory granules (SGs) that undergoes no residence time on plasma membrane before fusion and, to a lesser extent, also the predocked SGs.
Title: Syntaxin 2 Acts as Inhibitory SNARE for Insulin Granule Exocytosis.
The selectivity in syntaxin binding and apical protein redistribution further suggests that rab17 and syntaxin 2 mediate fusion of transcytotic vesicles at the apical surface.
Title: The GTP-bound and Sumoylated Form of the rab17 Small Molecular Weight GTPase Selectively Binds Syntaxin 2 in Polarized Hepatic WIF-B Cells.
It was concluded that Epim deletion inhibits polyposis in Apcmin/+ mice, associated with increased mucosal TGF-beta signaling and decreased myofibroblast HGF expression and secretion.

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_152615.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (5) contains an alternate exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
