HGNC Approved Gene Symbol: NOL4
Cytogenetic location: 18q12.1 Genomic coordinates (GRCh38) : 18:33,851,100-34,224,913 (from NCBI)
Ueki et al. (1998) cloned a cDNA encoding a novel nucleolar protein, NOL4, which they called NOLP, from a human fetal brain cDNA library. The NOLP gene encodes a 524-amino acid polypeptide with an E. coli helicase-homologous region, an acid-rich domain, 3 base-rich putative nuclear localization signals, a serine-rich region, and a coiled-coil domain. Northern blot analysis and RT-PCR revealed that NOLP was expressed as a 3.5-kb mRNA in fetal brain, adult brain, and testis. Deletion studies revealed that NOLP contains functional nuclear and nucleolar localization signals.
Using ESTs, Ueki et al. (1998) tentatively mapped the NOL4 gene to chromosome 18q12. In a study of sequence homology between human chromosome 20 and mouse chromosome 2, Zhu et al. (2003) placed the NOL4 gene on human chromosome 20.
Gross (2014) mapped the NOL4 gene to chromosome 18q12.1 based on an alignment of the NOL4 sequence (GenBank BC000313) with the genomic sequence (GRCh37).
