Function: 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).
Subunit Structure: Component of the CAVIN complex composed of CAVIN1, CAVIN2, CAVIN3 and CAVIN4. Homotrimer (By similarity). Interacts with TTF1 (PubMed:9582279). Interacts with RNA polymerase I. Binds the 3' end of pre-rRNA. Interacts with transcription factor ZNF148 (By similarity). Interacts with LIPE in the adipocyte cytoplasm (PubMed:17026959). Interacts with CAV1 and CAVIN3 (By similarity). Interacts with CAVIN2 (PubMed:19525939, PubMed:24567387). Interacts with CAVIN4 and CAV3 (PubMed:24567387).
Post-translational Modifications: Phosphorylated. Present in active and inactive forms. Changes in phosphorylation pattern may alter activity. Phosphorylation at Tyr-156 is essential for its functionin the regulation of ribosomal transcriptional activity.Five truncated forms are found in the caveolae. These are thought to be the result of proteolysis and may be phosphorylation-dependent. Monoubiquitinated.
Similarity: The leucine-zipper domain 1 is essential for its localization in the caveolae. Belongs to the CAVIN family.

This gene encodes a protein that enables the dissociation of paused ternary polymerase I transcription complexes from the 3' end of pre-rRNA transcripts. This protein regulates rRNA transcription by promoting the dissociation of transcription complexes and the reinitiation of polymerase I on nascent rRNA transcripts. This protein 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. This protein translocates from caveolae to the cytoplasm after insulin stimulation. Caveolae contain truncated forms of this protein and may be the site of phosphorylation-dependent proteolysis. This protein 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. [provided by RefSeq, Nov 2009]
