    Gene Group (FlyBase)
    KINETOCHORE MIS12 COMPLEX - NF1A VARIANT -
    The MIS12 complex is an outer kinetochore complex that bridges the inner kinetochore component CENP-C and the outer kinetochore Ndc80 complex. In Drosophila, there are two complex variants, one containing Nnf1a and one containing Nnf1b. (Adapted from FBrf0231098.)

    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.

    Testis-specificity index

    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).

          Other Comments

          RNAi screen using dsRNA made from templates generated with primers directed against this gene results in chromosome misalignment on the metaphase spindle and a spindle that is aberrantly long when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.
