Tubulin Tyrosine Ligase Like Protein 2 (TTLL2)

TTLL2 belongs to the tubulin--tyrosine ligase family.Product of a dubious CDS prediction. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.Probable tubulin polyglutamylase that forms polyglutamate side chains on tubulin. Probably acts when complexed with other proteins

Tubulin tyrosine ligase-like 1 gene (TTLL1), which maps to the chromosome region 22q13.1 and has been partially duplicated on three other acrocentric chromosomes: 13, 15 and 21. Likely TTLL1a corresponds to the 1.8 kb transcript that was detected in a wide range of tissues and has a stronger expression in heart, brain and testis. A 4.8 kb transcript was found only in brain tissues.
