Product Specific Information
Store vial at -20°C prior to opening. Aliquot contents and freeze at -20°C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature.
This product is stable for several weeks at 4°C as an undiluted liquid. Dilute only prior to immediate use.
Anti-PTRF antibody is specific towards Cavin 1 PTRF. A BLAST analysis suggests cross-reactivity with Human based on 100% sequence homology. Cross-reactivity with PTRF (polymerase I and transcript release factor) from other sources has not been determined.
Target Information
The polymerase I and transcript release factor (PTRF) enables the dissociation of paused ternary polymerase I transcription complexes from the 3′ end of pre-rRNA transcripts, regulating rRNA transcription by promoting the dissociation of transcription complexes and the re-initiation of polymerase I on nascent rRNA transcripts.
PTRF also localizes to caveolae at the plasma membrane and is thought to play a critical role in the formation of caveolae and the stabilization of caveolins, translocating from caveolae to the cytoplasm after insulin stimulation.
PTRF is also thought to modify lipid metabolism and insulin-regulated gene expression. Mutations in this gene result in a disorder characterized by generalized lipodystrophy and muscular dystrophy.
