DESCRIPTION

THUMPD1 functions as an adaptor protein for secondary modification of transfer RNA (tRNA) by cytosine acetylation (Sharma et al., 2015).

CLONING

Sharma et al.. (2015) reported that the deduced 353-amino acid THUMPD1 protein has a conserved tRNA-binding THUMP domain between amino acids 111 and 254.

GENE FUNCTION

Sharma et al. (2015) found that overexpression of human NAT10 (609221) restored tRNA acetylation in yeast lacking the tRNA adaptor protein Tan1, the ortholog of human THUMPD1. Knockdown of NAT10 reduced tRNA acetylation in HCT116 cells. Coprecipitation analysis of HCT116 cells revealed that NAT10 interacted directly with THUMPD1. NAT10 also acetylated cytosines in 18S ribosomal RNA (see 180450) in a THUMPD1-independent manner. Sharma et al. (2015) proposed that THUMPD1 functions like Tan1 as a specific adaptor to mediate NAT10-dependent tRNA acetylation.

MAPPING

Hartz (2015) mapped the THUMPD1 gene to chromosome 16p12.3 based on an alignment of the THUMPD1 sequence (GenBank GENBANK AK000281) with the genomic sequence (GRCh38). ... More on the omim web site
