Ring Finger Protein 130 (RNF130)

RNF130 contains a RING finger motif and is similar to g1, a Drosophila zinc-finger protein that is expressed in mesoderm and involved in embryonic development. The expression of the mouse counterpart was found to be upregulated in myeloblastic cells following IL3 deprivation, suggesting that this gene may regulate growth factor withdrawal-induced apoptosis of myeloid precursor cells. G1RP is homologous to g1, a Drosophila melanogaster zinc-finger protein that is expressed in the mesoderm. Northern blot analysis using RNAs derived from 32Dcl3 cells that have been grown in the absence of IL-3 demonstrates that the G1RP message is upregulated in these cells following the removal of IL-3, suggesting that this gene may regulate growth factor withdrawal-induced apoptosis of myeloid precursor cells.
