Genes affected
RAB4B (HGNC:9782): (RAB4B, member RAS oncogene family) Predicted to enable G protein activity and GTP binding activity. Involved in glucose import. Located in insulin-responsive compartment; perinuclear region of cytoplasm; and recycling endosome. [provided by Alliance of Genome Resources, Apr 2022]
RAB4B-EGLN2 (HGNC:44465): (RAB4B-EGLN2 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring RAB4B (RAB4B, member RAS oncogene family) and EGLN2 (egl nine homolog 2) genes on chromosome 19. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
MIA-RAB4B (HGNC:48352): (MIA-RAB4B readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring MIA (melanoma inhibitory activity) and RAB4B (RAB4B, member RAS oncogene family) genes on chromosome 19. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
