Annotation Priorities

  • 1. Issues on the curation tracker
  • 2. Annotation improving networks inferred from GO:
    • i) substrates
    • ii) physical interactions
    • iii) complexes
  • 3. Phenotype screens see ​canto (big bang for buck)
  • 4. Processes mature enough to build pathways: usually those which have a large percentage of functionally characterised genes (for example mitochondrion organization has 40 published genes/294, so is low priority, compared to cytokinesis 136/139)
    • chromosome segregation (Val)
    • DNA metabolism (Midori)
    • cytokinesis (Val)
    • regulation of mitotic cell cycle (All)
    • signaling pathways (Antonia)
    • chromatin organization (All)
    • cell polarity
  • 5. New gene characterizations -These should be sent out for community curation, but followed up

dis1 PMID:16920624 plus…XMAP215/ TOG/Stu2-family homolog, binds microtubules and localizes to kinetochores (Nakaseko et al., 2001). Mutants in dis1 lack the chromosome alignment phase in metaphase and arrest with elongated spindles and segregated but unseparated chromosome pairs (Nabe- shima et al., 1998; Ohkura et al., 1988).dis1 mutants arrest with an activated spindle checkpoint and appear to ex- perience an increase in sister chromatid cosegregation (70%) at full restrictive temperature. Such cosegregation results when mono-oriented attachment of sister kineto- chores to microtubules from the same SPB is not corrected. Since dis1 mutants lack the phase of constant spindle length when chromosomes are properly aligned -
dis2 phosphatase (PMID:14765108 - describes checkpoint termination Dis2 abrogates Chk1 phosphorylation and activation in vivo, ) PMID:2245912 PMID:8389306 PMID:8305731 PMID:7983142 PMID:7957097 PMID:9264466 PMID:9790575 PMID:10668632 PMID:11085271 PMID:16411888 PMID:17895368 PMID:19592249 PMID:21664573 (Out for CC PMID:21703453 PMID:21965289 PMID:23333317) (Iain Hagan PMID:25487150) -
cut7In the temperature-sensitive cut7 mutant, spindle formation is blocked shortly after duplication of the SPB. The mitotic spindle radiating from the opposite poles cannot interdigitate and thus remains as a V shape (Hagan and Yanagida, 1992). The cut7- specific defect generates a condition whereby the bipolar attachment of the spindle to kinetochores is not achieved. Previously, we demonstrated that this defect causes an arrest in a mad2+-dependent manner (Kim et al., 1998). At the restrictive temperature the majority of Mad2-GFP was found on condensed chromosomes as one or more speckles (Fig. 4).

Notes and annotation questions on chromosome segregation

  • read review PMID: 23512483
  • is CENP-A containing nucleosome assembly part of kinetochore assembly? Although the outer repeats play an important role in sister centromere cohesion and possibly help to properly orient the multiple kinetochore microtubule attachment sites (Pidoux and Allshire, 2004
  • Centromeres: getting a grip of chromosomes. Curr. Opin. Cell Biol. 12, 308–319., the central region is needed for the assembly of the kinetochore per se and the interaction with the mitotic spindle fibers
  • what is the relationship between kinetochoe assembly, spindle elongation and chromosome segregation (currently disjoint)
  • reannotate ndc80 and MIND subcomplexes annotate PAS complex
  • ask expert to look at CENP_A assembly vs CENP-A assembly phenotype
  • no substrates currently annotated for APC, look for motifs ABBA, KENm D-Box, C-BOX, F-box, 2BR, LRRL
    • I think from humanUbc11 is the APC E2, has some substrates assigned (cdc13 direct, slp1 indirect), but sc imlies ubc4 and ubc1 (amybe all)
  • possible substrates to annotate mitotic securin and cylin; late mitosis cdh1 , cytokinesis aurora, cyclins, cdc29; G1 geminin, cdc6, skp2,ubcH10(ubc11)
  • check all know APC targets annotated

Notes and annotation questions on cytokinesis

  • previously considered to be linear assembly mid1- rng2- others. But if you can ectopically localize rng2 you can get all of the others (any one of the 3 will work)
  • check should mid1 be ring assemlby or localization only?
check mid1 NOT assembly? positioning
main target of mid1 is rng2 rng3- myosin specific chaperone add to wiki with mohan paper details

Notes and annotation questions on cell cycle regulation

  • Only include gene products here not covered in chromosome segregation, cytokinesis or DNA metabolism
  • genes which should be annotated to "signalling" based on the signalling components of the cell cycle regulation network
  • Need to do cytokinesis checkpoint, G1 cell size control checkpoint, DNA damage checkpoint (ask experts to check specific checkpoint lists)
