Protein names

Tumor protein p73 , p53-like transcription factor , p53-related protein

Protein function

Participates in the apoptotic response to DNA damage. Isoforms containing the transactivation domain are pro-apoptotic, isoforms lacking the domain are anti-apoptotic and block the function of p53 and transactivating p73 isoforms. May be a tumor suppressor protein. / Zn2+

Protein tissue specificity

Expressed in striatal neurons of patients with Huntington disease (at protein level). Brain, kidney, placenta, colon, heart, liver, spleen, skeletal muscle, prostate, thymus and pancreas. Highly expressed in fetal tissue.

Protein sequence and domain

Possesses an acidic transactivation domain, a central DNA binding domain and a C-terminal oligomerization domain that binds to the ABL1 tyrosine kinase SH3 domain. / The WW-binding motif mediates interaction with WWOX. / Belongs to the p53 family. / Contains 1 SAM (sterile alpha motif) domain.

Protein post-translational modifications

Isoform alpha (but not isoform beta) is sumoylated on Lys-627, which potentiates proteasomal degradation but does not affect transcriptional activity. Phosphorylation by PLK1 and PLK3 inhibits the transcription regulator activity and pro-apoptotic function. / Higher levels of phosphorylation seen in the brain from patients with Huntington disease. / Polyubiquitinated by RCHY1/PIRH2; leading to its degradation by the proteasome.
