Genes affected
TTI2 (HGNC:26262): (TELO2 interacting protein 2) This gene encodes a regulator of the DNA damage response. The protein is a component of the Triple T complex (TTT) which also includes telomere length regulation protein and TELO2 interacting protein 1. The TTT complex is involved in cellular resistance to DNA damage stresses and may act as a regulator of phosphoinositide-3-kinase-related protein kinase (PIKK) abundance.

MAK16 (HGNC:13703): (MAK16 homolog) Enables RNA binding activity. Predicted to be involved in maturation of 5.8S rRNA and maturation of LSU-rRNA. Located in nucleolus. [provided by Alliance of Genome Resources, Apr 2022]
