Genes affected
SDF2 (HGNC:10675): (stromal cell derived factor 2) The protein encoded by this gene is believed to be a secretory protein. It has regions of similarity to hydrophilic segments of yeast mannosyltransferases. Its expression is ubiquitous and the gene appears to be relatively conserved among mammals. Alternate splicing results in both coding and non-coding variants. A pseudogene of this gene is located on chromosome 15. [provided by RefSeq, Dec 2011]
SUPT6H (HGNC:11470): (SPT6 homolog, histone chaperone and transcription elongation factor) Enables histone binding activity. Involved in negative regulation of histone H3-K27 methylation and positive regulation of transcription elongation from RNA polymerase II promoter. Predicted to be located in nucleoplasm. Predicted to be part of transcription elongation factor complex. Predicted to be active in transcriptionally active chromatin. [provided by Alliance of Genome Resources, Apr 2022]
