PUS7

Function

Pseudouridylate synthase that catalyzes pseudouridylation of RNAs (PubMed:28073919, PubMed:29628141, PubMed:30778726). Acts as a regulator of protein synthesis in embryonic stem cells by mediating pseudouridylation of RNA fragments derived from tRNAs (tRFs): pseudouridylated tRFs inhibit translation by targeting the translation initiation complex (PubMed:29628141). Also catalyzes pseudouridylation of mRNAs: mediates pseudouridylation of mRNAs with the consensus sequence 5'-UGUAG-3' (PubMed:28073919). In addition to mRNAs and tRNAs, binds other types of RNAs, such as snRNAs, Y RNAs and vault RNAs, suggesting that it can catalyze pseudouridylation of many RNA types (PubMed:29628141).

Involvement in disease

Intellectual developmental disorder with abnormal behavior, microcephaly, and short stature

IDDABS

An autosomal recessive disorder characterized by intellectual disability, developmental delay with poor or absent speech, short stature, progressive microcephaly, hyperactivity and aggressive behavior. Some patients manifest sensorineural hearing loss.

None

The disease is caused by variants affecting the gene represented in this entry.
