The gene centromere identifier is referred to in FlyBase by the symbol Dmel\cid (CG13329, FBgn0040477). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: microtubule motor activity. There is experimental evidence that it is involved in the biological process: mitotic metaphase plate congression; mitotic spindle elongation; kinetochore assembly; chromosome segregation; mitosis; mitotic spindle organization; kinetochore organization; spindle assembly; neurogenesis. 26 alleles are reported. The phenotypes of these alleles are annotated with: cell cycle; cell cycle process; external compound sense organ; organelle; organ system subdivision; M phase; nucleus; cellular process; sense organ; nuclear part; eo support cell; cellular component organization or biogenesis. It has one annotated transcript and one annotated polypeptide. Protein features are: Histone H3; Histone core; Histone-fold. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of very low expression. Peak expression observed within 00-06 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: adult ovary. Comments on Affy2 ProbeSet: ProbeSet 1625258_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of cid. Gene sequence location is 2R:9373122..9374136.

Comment:Localization observed at interphase and during mitosis; assayed in S2R+ cells
Additional Descriptive Data
Protein can be detected as 4 distinct foci of staining at the centromere region of chromatids of developing spermatozoa. While staining cannot be detected in very late spermatids and mature spermatozoa, the highly compact nature of the sperm nuclei have been shown to exclude antibodies and therefore prevent visualization of proteins associated with these structures. Shortly after fertilization protein can be detected again as discrete spots on the apposed pronuclei.

RNAi screen using dsRNA made from templates generated with primers directed against this gene results in chromosome misalignment on the metaphase spindle and the formation of aberrantly long spindles when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.
New incorporation of cid protein into centromeres takes place during anaphase of the syncytial divisions of embryos. This incorporation is independent of DNA replication and of normal pulling forces generated by the mitotic spindle, but is strictly coupled to mitotic progression.
