WD repeat-containing protein 74 (WDR74)

Regulatory protein of the MTREX-exosome complex involved in the synthesis of the 60S ribosomal subunit (PubMed:26456651). Participates in an early cleavage of the pre-rRNA processing pathway in cooperation with NVL (PubMed:29107693).

Required for blastocyst formation, is crucial for RNA transcription, processing and/or stability throughout preimplantation development (By similarity). .
