2.3.1.108 | Tetrahymena thermophila | construction of a Mec-17 disruption mutant. The MEC-17-KO Tetrahymena cells have a normal growth rate, but theMEC-17-KOcells grow more slowly than wild type on medium with the microtubule depolymerizing compound oryzalin. Conversely, the MEC-17 KO cells grew faster than wild-type cells in medium with paclitaxel, a microtubule-stabilizing drug. This drug phenotype is consistent with an increase in dynamics of microtubules in MEC17-KO cells | additional information |

2.3.1.108 | malfunction | disruption of the Tetrahymena MEC-17 gene, resulting in a marked loss of acetyl-K40 in Tetrahymena cells, phenocopies the K40R alpha-tubulin mutation and makes microtubules more labile. Overexpression of GFP-Mec17p in Tetrahymena greatly increases acetylation of microtubules | Tetrahymena thermophila |
2.3.1.108 | malfunction | MEC-12 is the only alpha-tubulin with K40, and mec-12(e1607) probable null allele worms have greatly reduced touch responses. Intergration of single transgenes encoding MEC-12 with either wild-type K40 or K40R or K40Q substitutions into the mec-12(e1607)mutant using Mos1 transposon excision repair restores the levels of touch response to 80% of wild type level,whereas animals with either MEC-12-K40R or MEC-12-K40Q show reduced touch response, overview | Caenorhabditis elegans |
2.3.1.108 | malfunction | zebrafish embryos depleted in MEC-17 show a dramatic loss of acetyl-K40 in neurons but not in cilia. Depletion of MEC-17 in zebrafish, by injection with random sequence morpholinos or 5-bp mismatched morpholinos, produces phenotypes consistent with neuromuscular defects | Danio rerio |
2.3.1.108 | additional information | MEC-17 sequences are absent from Chlamydomonas reinhardtii, an organism that has alphaTAT activity | Chlamydomonas reinhardtii |
2.3.1.108 | physiological function | MEC-17 is required for the function of touch receptor neurons in Caenorhabditis elegans and acts as a K40-specific acetyltransferase for alpha-tubulin. W06B11.1 os also required for acetylation of K40 and contribute to touch sensation | Caenorhabditis elegans |
2.3.1.108 | physiological function | the K40 residue of alpha-tubulin is important in vertebrates, acetyl-K40-carrying microtubules are abundant in the nervous system, including the brain, optical nerves, spinal cord, and axons of peripheral nerves. MEC-17 is required for K40 acetylation in zebrafish and normal embryonic development | Danio rerio |
