Supplementary information

PTRF also known as Cavin-1 is a protein with a mass of approximately 43 kDa. It functions primarily as a regulator of caveolae formation and stability. Caveolae are small flask-shaped invaginations in the plasma membrane. PTRF interacts directly with caveolin proteins to facilitate caveolae assembly. It is largely expressed in adipose tissue muscle tissue and endothelial cells indicating a significant role in cellular processes in these cells.
Biological function summary

PTRF facilitates various processes like signal transduction and lipid metabolism due to its role in caveolae function. As part of the caveolae complex it is essential for maintaining structural integrity and organization. PTRF interacts with other proteins such as cavin family members and caveolins aiding in cellular response to mechanochemical stimuli. By regulating the caveolae PTRF influences activities including endocytosis and potocytosis.

Pathways

PTRF is critical in cholesterol homeostasis and endothelial nitric oxide synthase (eNOS) signaling pathways. It associates with caveolin-1 modulating these pathways to balance lipid composition and promote endothelial function. The interaction between PTRF and caveolin-1 enhances nitric oxide production which is important for vascular tone regulation and cellular stress response. This positions PTRF as a regulator in cardiovascular and metabolic pathways.

Defects or deficiencies in PTRF can lead to disorders such as lipodystrophy and muscular dystrophy. The absence or malfunction of PTRF disrupts normal caveolae structure leading to impaired lipid storage and muscle function. PTRF's interaction with caveolin-1 connects it to cardiovascular diseases as caveolin-1 mutations contribute to the pathogenesis of cardiac dysfunction. Understanding PTRF's role offers insights into therapeutic strategies for these conditions.

Target data

Plays an important role in caveolae formation and organization. Essential for the formation of caveolae in all tissues (PubMed : 18056712, PubMed : 18191225, PubMed : 19726876). Core component of the CAVIN complex which is essential for recruitment of the complex to the caveolae in presence of calveolin-1 (CAV1). Essential for normal oligomerization of CAV1. Promotes ribosomal transcriptional activity in response to metabolic challenges in the adipocytes and plays an important role in the formation of the ribosomal transcriptional loop. Dissociates transcription complexes paused by DNA-bound TTF1, thereby releasing both RNA polymerase I and pre-RNA from the template (By similarity) (PubMed : 18056712, PubMed : 18191225, PubMed : 19726876). The caveolae biogenesis pathway is required for the secretion of proteins such as GASK1A (By similarity).
