Official Symbol: mec-12
Official Full Name: Detyrosinated tubulin alpha-3 chain
Primary source: WormBase:WBGene00003175
Locus tag: CELE_C44B11.3
See related: AllianceGenome:WB:WBGene00003175
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Predicted to enable GTP binding activity. Predicted to be a structural constituent of cytoskeleton. Involved in several processes, including detection of mechanical stimulus involved in sensory perception of touch; positive regulation of detection of mechanical stimulus involved in sensory perception of touch; and positive regulation of mechanosensory behavior. Located in axon; microtubule; and neuronal cell body. Is expressed in intestine; nervous system; and in male. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis type 22; keratoconus; lissencephaly (multiple); microcephaly; and visual epilepsy. Orthologous to several human genes including TUBA3C (tubulin alpha 3c) and TUBA3D (tubulin alpha 3d). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

tubulin acetylation and microtubule protofilaments were unaffected in the mec-12(gm379) mutant. We hypothesize that the G416E substitution may alter the association of microtubule-binding proteins with microtubules

Acetylation of MEC-12 alpha-tubulin constrains protofilament number in C. elegans touch receptor neurons.
Title: Posttranslational acetylation of α-tubulin constrains protofilament number in native microtubules.
Data show that all mec-15 phenotypes can be dominantly suppressed by mutations in mec-7, which encodes a beta-tubulin, and dominantly enhanced by mutations in mec-12, which encodes an alpha-tubulin.
Title: mec-15 encodes an F-box protein required for touch receptor neuron mechanosensation, synapse formation and development.
