Gene Snapshot

Protein Function (UniProtKB)

Part of the HipHop-HOAP complex that recruits the MTV complex to form the terminin telomere-capping complex, which binds to chromosome ends in a sequence-independent manner and prevents telomere fusion (PubMed:11408576, PubMed:12510197, PubMed:12826664, PubMed:19181850, PubMed:19190990, PubMed:20057353). Telomere capping is independent of the origin recognition complex (ORC) (PubMed:12510197).

(UniProt, Q95RV2)

Summary (Interactive Fly)

poorly conserved component of the telomere capping complex - prevents end fusion by maintaining a chromatin state that is independent of the underlying DNA sequence

Model Confidence:

Very high (pLDDT > 90)
Confident (90 > pLDDT > 70)
Low (70 > pLDDT > 50)
Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Subunit Structure (UniProtKB)

Component of the HipHop-HOAP telomere capping complex, composed of at least HipHop and cav/HOAP, and may include Su(var)205/HP1; HipHop and cav/HOAP, but not Su(var)205, are interdependent for their protein stability (PubMed:20057353). Interacts with HipHop (via N-terminus) (PubMed:20057353). Interacts (via C-terminus) with Su(var)205/HP1 dimer (via hinge and chromoshadow domain) and Orc1; possibly interacts with other components of the origin recognition complex (ORC) (PubMed:11408576, PubMed:12826664, PubMed:19181850). Each molecule of cav/HOAP interacts with 2 molecules of Su(var)205/HP1 (PubMed:12826664). The HipHop-HOAP complex recruits the MTV complex, consisting of moi/modigliani, tea and ver/verrocchio, to telomeres, forming the terminin telomere-capping complex (PubMed:19181850, PubMed:20679394). Interacts with moi/modigliani; the interaction is direct (PubMed:19181850). Interacts with ver/verrochio; the interaction is direct (PubMed:20679394). Interacts with HP6, which is also part of the terminin complex (PubMed:19190990). Interacts (via N-terminus) with peo/pendolino (via N-terminus); the interaction is direct (PubMed:26110638).

Etymology

The gene is named "caravaggio", because the linear multicentric chromosomes that characterize the mutant phenotype resemble little trains; there is an Italian train named "Caravaggio" in memory of the famous painter.

(Cenci et al., 2003)

Named "caravaggio" after an Italian train, as the multicentric chromosomes observed in mutants resemble little trains of chromosomes.
