Genes affected

PROX2 (HGNC:26715): (prospero homeobox 2) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

PROX2 links:

YLPM1 (HGNC:17798): (YLP motif containing 1) Enables RNA binding activity. Predicted to be involved in regulation of telomere maintenance. Predicted to act upstream of or within negative regulation of transcription by RNA polymerase II. Located in cytosol and nuclear speck. [provided by Alliance of Genome Resources, Apr 2022]
