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 PPxY motif mediates interaction with WWOX.
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. Is an activator of FOXJ1 expression (By similarity). It is an essential factor for the positive regulation of lung ciliated cell differentiation (PubMed:34077761).
Ciliary dyskinesia, primary, 47, and lissencephaly
CILD47
A form of primary ciliary dyskinesia, a disorder characterized by abnormalities of motile cilia. Respiratory infections leading to chronic inflammation and bronchiectasis are recurrent, due to defects in the respiratory cilia. CILD47 is an autosomal recessive form characterized by onset soon after birth or in early childhood. Affected individuals also have neurologic features, such as impaired intellectual development and central hypotonia, associated with structural brain abnormalities, most notably lissencephaly and thin or absent corpus callosum. No situs abnormalities have been observed.
None
The disease is caused by variants affecting the gene represented in this entry.
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.
Belongs to the p53 family.
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. Expressed in the respiratory epithelium (PubMed:34077761).
