Mouse Anti-TP73 Recombinant Antibody (CBYJT-4294) (CBMAB-T3774-YJ)

TP73

TP73 is a member of the p53 family of transcription factors involved in cellular responses to stress and development. It maps to a region on chromosome 1p36 that is frequently deleted in neuroblastoma and other tumors, and thought to contain multiple tumor suppressor genes. The demonstration that TP73 is monoallelically expressed (likely from the maternal allele), supports the notion that it is a candidate gene for neuroblastoma.

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.

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.
