Selenoprotein evolution: update blog

This cluster of genomeWiki articles on selenoprotein evolution in vertebrates is updated regularly by various contributers. Because those changes can be scattered across diverse long articles, this simple directory to articles and significant updates can be helpful for following developments.

• Tracking significant updates (this page)
• Selenoprotein curated sequence collection
• Evolution of GPX glutathione peroxidases
• SECIS elements, binding proteins, and selenocysteine insertion

Reverse Chronological Update Blog

28 May 08 (Tom): added GPX3 in two further marsupials (still no GPX5 or GPX6); located 17 SECIS elements for each of GPX1 and GPX2
26 May 08 (Tom): began new page on detailed evolution of glutathione peroxidases based on 240 sequences
25 May 08 (Tom): added GPX sequences from urchin, amphioxus, tunicate, lamprey, and chondrichthyes; assimilated Perry's GPX sequences
23 May 08 (Tom): brought SELI to 10 deuterostome sequences
22 May 08 (Tom): upped GPX4 collection to 26 coding and 14 SECIS sequences
21 May 08 (Tom): added 30 GPX8 sequences (all cysteine except serine in most fish)
20 May 08 (Tom): located SECIS elements for GPX3, added screenshots of 3' UTR context.
18 May 08 (Tom): added 78 seqs for GPX3 and GPX5-GPX6 inverted tandem, patterns of U loss, fixed GPX classifer.
16 May 08 (Tom): found a new SECIS binding protein KIAA0256; moved all things SECIS to a new page
14 May 08 (Tom): moved stuff around, added summary matrix for genome project species, fixed fasta headers
14 May 08 (Perry): Put all GPX sequences I've collected into one group-not formatted correctly, just present for reference
12 May 08 (Tom): parsed TXNRD1-3 exons in human and added about 30 species each for terminal GCuG exons.
11 May 08 (Tom): found metazoan outgroup species with selenocysteine in SELU3 and additional lophotrochozoans for SELU2
10 May 08 (Tom): fixed SELK, added new SeCis collection, integrated hagfish/lamprey/eshark collections
09 May 08 (Tom): added 15 SEPP1, colorized the selenocysteines for clarity
08 May 08 (Perry): In the AM, added some to GPx1 and GPx2
08 May 08 (Perry): Started sections for the remaining human selenoproteins
08 May 08 (Tom): Started sections on SELO, SEPN1, SEPHS1, SEPHS2, SELK, SELT, GPX1, etc
06 May 08 (Tom): Added special section on basal jawless vertebrates: 16 genes from lamprey, 8 from hagfish.
28 Apr 08 (Tom): Brought total sequence count to 341, greatly expanded DIO1 and SELV collections and gene highlights
25 Apr 08 (Tom): Fixed DIO deiodinase sequences
24 Apr 08 (Tom): Added echidna and platypus selenoproteins from 454 search
