Rb188, DMAP190, Cen190, CP-190, Centrosomal Protein 190
BTB/POZ domain and microtubule binding protein that alternatively serves as a chromatin insulator and as a component of centrioles - involved in axial expansion, the spreading out along the anterior-to-posterior axis during syncytial development

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

Homodimerizes via the N-terminal BTB domain (PubMed:26649574). Component of the gypsy chromatin insulator complex, composed of Cp190, mod(mdg4) and su(Hw) (PubMed:15574329). The gypsy chromatin insulator complex interacts with Topors via mod(mdg4) and su(Hw) (PubMed:15574329). Interacts with Cp60 (PubMed:8491775, PubMed:8590797, PubMed:9700165). Interacts with inv (PubMed:25561495). Interacts with Nup98 (PubMed:28366641). Interacts (via BTB domain) with pita (via region between the ZAD domain and the first zinc finger domain); the interaction is direct (PubMed:25342723, PubMed:33752739). Interacts with ZIPIC (via region between the ZAD domain and the first zinc finger domain); the interaction is direct (PubMed:25342723). Interacts (via regions between the BTB domain and first zinc finger domain) with cliff (via regions flanking MADF domain 1); the interaction is probably direct (PubMed:38769058). Associates (via N-terminus) with microtubules; the interaction is direct, is enhanced by dimerization and involves multiple regions within the N-terminus (PubMed:14996941, PubMed:26649574, PubMed:8491775, PubMed:8522588). Microtubule association is enriched at growing plus ends (PubMed:26649574).

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
Comment: reported as ventral nerve cord anlage

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

Map60
The introduction of dsRNA made from templates generated with primers directed against this gene into S2 cells prevents the accumulation of Map60 to mitotic centrosomes.
Cp190 plays an essential role in flies that is independent of its association with centrosomes or microtubules.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
Fluorescently labelled bacterially expressed Cp190 is injected into living embryos and protein behaviour during the rapid syncytial blastoderm divisions (nuclear cycles 10-13) is followed.
The localisation of Cp190 protein within the fertilised egg has been studied.
The region between amino acids 385 and 508 of the Cp190 protein is sufficient for good centrosomal localisation. A nuclear localisation domain is located between amino acids 201 and 271.
By using monoclonal antibodies that recognize protein components of the mitotic apparatus to screen expression libraries, Cen185, which encodes a protein associated with the centrosome, was cloned.
