MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] TTL is a cytosolic enzyme involved in the posttranslational modification of alpha-tubulin (see MIM 602529). Alpha-tubulin within assembled microtubules is detyrosinated over time at the C terminus. After microtubule disassembly, TTL restores the tyrosine residues and consequently participates in a cycle of tubulin detyrosination and tyrosination (Erck et al., 2003 [PubMed 14571137]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Homozygous null mice display neonatal lethality, impaired breathing, and fail to form the internal capsule in the brain. [provided by MGI curators]
