Genes affected

ANKRD54 (HGNC:25185): (ankyrin repeat domain 54) Predicted to enable protein kinase regulator activity. Predicted to be involved in positive regulation of erythrocyte differentiation; regulation of intracellular signal transduction; and regulation of protein kinase activity. Predicted to act upstream of or within nucleocytoplasmic transport. Predicted to be located in midbody. Predicted to be active in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

MIR659 (HGNC:32915): (microRNA 659) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]
