Genes affected

CSDE1 (HGNC:29905): (cold shock domain containing E1) Enables RNA stem-loop binding activity. Involved in IRES-dependent viral translational initiation; nuclear-transcribed mRNA catabolic process, no-go decay; and stress granule assembly. Located in Golgi apparatus; cytosol; and plasma membrane. Part of CRD-mediated mRNA stability complex. [provided by Alliance of Genome Resources, Apr 2022]
