Nomenclature changes

19AUG2022

Gene symbol changed from "XB940519 [provisional:pak2]" to "pak2 (provisional)".

"XB940519" was added as a gene synonym.

Gene name changed from "provisional ortholog of p21 (RAC1) activated kinase 2" to "p21 (RAC1) activated kinase 2 (provisional)".

22MAy2023 Xenopus gene synbol and name changed from pak2 (provisional), p21 (RAC1) activated kinase 2 (provisional to pak2l, p21 (RAC1) activated kinase 2 like.


synteny and orthology

pak2l in X. tropicalis and pak2l in X. laveis.L are on different chromsomes and 'do not share a syntenic, or common/conserved group of genes flanking them in the v10 genome assemblies. Here I compare synteny on the paralogous chromosome to see if we can better annotate these genes.

Conclusions:

  • LOC121402941(unch)and LOC108713857(unch): DIOPT/Eggnog matches both these protein to ~100 bacterial proteins from 63 species (ie these are NOT a PAK2 genes)
  • No candidate genes are annotated on Xla. Chromsomome 4L or Chromsomome 4S that would be an alternative 'best match' for pak2l gene page.
  • Similarly, there is no X.tropicalis or Xlaevis.S candidate genes on Chr7/7S that would justify a new gene page.
  • These genes can stay on this pak2-like gene page


NOTE THAT TRUE PAK2 - p21 (RAC1) activated kinase 2 ORTHOLOGs IN XENOPUS are Xtrop Gene ID: 733718, X.laevis.L Gene: 108717139, and X.laevis.S Entrez Gene: 399090 ON CHROMOSOME 5/5L/5S.

Note the conserved upstream flanking genes, NRROS and FBXO45.
