Component of gems 4 is a protein that in humans is encoded by the GEMIN4 gene.[1][2]

The product of this gene is part of a large complex localized to the cytoplasm, nucleoli, and to discrete nuclear bodies called Gemini bodies (gems). The complex functions in spliceosomal snRNP assembly in the cytoplasm, and regenerates spliceosomes required for pre-mRNA splicing in the nucleus. The encoded protein directly interacts with a DEAD box protein and several spliceosome core proteins. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.[2]

Interactions[edit]

GEMIN4 has been shown to interact with DDX20,[1][3][4] EIF2C2,[4][5] LGALS1[6] and SMN1.[3][7]
