Required for processing of pre-rRNA and maturation of 40S ribosomal subunits. Mature tissues, such as adult brain, skeletal muscle, heart, and kidney, express low levels, whereas tissues and organs with significant populations of proliferating cells, such as fetal brain, placenta, bone marrow, and various glandular organs, contain significantly higher levels. The disease is caused by variants affecting the gene represented in this entry. Belongs to the eukaryotic ribosomal protein eS24 family.
