Summary: This gene encodes a member of the tubulin tyrosine ligase like protein family. This protein interacts with two glucocorticoid receptor coactivators, transcriptional intermediary factor 2 and steroid receptor coactivator 1. This protein may function as a coregulator of glucocorticoid receptor mediated gene induction and repression. This protein may also function as an alpha tubulin polyglutamylase.[provided by RefSeq, Feb 2010]
Expression: Broad expression in testis (RPKM 39.2), thyroid (RPKM 5.0) and 22 other tissues See more

in a study of 3 family members from 2 generations, identified in a previously misdiagnosed incomplete congenital stationary night blindness (icCSNB) case a splice-site mutation in intron 3 of TTLL5 (c.182-3_182-1delinsAA); reinvestigation of the clinical data corrected the diagnosis to cone dystrophy
Title: Novel splice-site mutation in TTLL5 causes cone dystrophy in a consanguineous family.
5 homozygous variants [p.(Asp594fs), p.(Gln117*), p.(Met712fs), p.(Ile756Phe) and p.(Glu543Lys)] in TTLL5, in 8 patients from 6 families were identified. 2 male patients carrying truncating TTLL5 variants also displayed a reduction in sperm motility and infertility, whereas those carrying missense changes were fertile. TTLL has multiple viable isoforms, being highly expressed in retina, testis and spermatozoon flagellum.
Title: Mutations in the polyglutamylase gene TTLL5, expressed in photoreceptor cells and spermatozoa, are associated with cone-rod degeneration and reduced male fertility.
this study has performed exome sequencing in 28 individuals with a similar disease phenotype and subsequently used a casecontrol approach to identify mutations in TTLL5 as a cause of recessive retinal dystrophy.

This study indicates that a physiological function of STAMP in several settings is to modify cell growth rates in a manner that can be independent of steroid hormones.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
