Genes affected

TPPP2 (HGNC:19293): (tubulin polymerization promoting protein family member 2) Enables tubulin binding activity. Involved in regulation of flagellated sperm motility. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

TPPP2 links:

NDRG2 (HGNC:14460): (NDRG family member 2) This gene is a member of the N-myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. The protein encoded by this gene is a cytoplasmic protein that may play a role in neurite outgrowth. This gene may be involved in glioblastoma carcinogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2017]
