Genes affected

HCLS1 (HGNC:4844): (hematopoietic cell-specific Lyn substrate 1) Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and protein kinase binding activity. Involved in several processes, including positive regulation of intracellular signal transduction; positive regulation of protein phosphorylation; and regulation of transcription, DNA-templated. Located in cytosol; nucleus; and plasma membrane. Part of transcription regulator complex. [provided by Alliance of Genome Resources, Apr 2022]
