Gene Information
mouse ... PTRF(19285)
General description
Polymerase I and transcript release factor (PTRF) contains a leucine zipper motif, a nuclear localization signal, and PEST domains. It is critically involved in termination of transcription by stalling RNA poly I and releasing it from the elongating transcript. PTRF is also found localized to caveolae and regulates formation of the vesicles at the plasma membrane.
Immunogen
Synthetic peptide directed towards the middle region of mouse PTRF
Biochem/physiol Actions
In mouse, pausing of elongation complexes is mediated by the transcription termination factor TTF-I bound to the ′Sal box′ terminator downstream of the rDNA transcription unit. PTRF is a Pol I and transcript release factor for dissociation of paused ternary complexes.
Sequence
Synthetic peptide located within the following region: SEALPEKEGDELGEGERPEDDTAAIELSSDEAVEVEEVIEESRAERIKRS
Physical form
Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.

Caveolae are small membrane invaginations important for cell signaling that are characterized by the presence of caveolin proteins. Hill et al. (2008) have now identified PTRF as a new constituent of the caveolar coat. In the absence of PTRF, caveolae

Termination of transcription by RNA polymerase I (Pol I) is a two-step process which involves pausing of elongating transcription complexes and release of both pre-rRNA and Pol I from the template. In mouse, pausing of elongation complexes is mediated by

Caveolae are small invaginated pits that function as dynamic mechanosensors to buffer tension variations at the plasma membrane. Here we show that under mechanical stress, the EHD2 ATPase is rapidly released from caveolae, SUMOylated, and translocated to the nucleus, where

Caveolae are abundant surface organelles implicated in a range of cellular processes. Two classes of proteins work together to generate caveolae: integral membrane proteins termed caveolins and cytoplasmic coat proteins called cavins. Caveolae respond to membrane stress by releasing cavins

Caveolae-associated protein 3 (cavin3) is inactivated in most cancers. We characterized how cavin3 affects the cellular proteome using genome-edited cells together with label-free quantitative proteomics. These studies revealed a prominent role for cavin3 in DNA repair, with BRCA1 and BRCA1
