Supplementary information

The protein p73 also known in scientific literature as p-73 or simply p 73 is a member of the p53 family of transcription factors. Molecular weight of p73 is approximately 80 kDa. It is expressed widely in human tissues with high levels observed in the brain kidneys and heart. Structurally p73 is similar to p53 and shares many functional domains including a DNA-binding domain and an oligomerization domain.
Biological function summary

P73 plays a significant role in regulating cell cycle and apoptosis. It can activate transcription of several genes involved in these processes. p73 does not function alone; it can form complexes with other p53 family members and modulate cellular responses to stress. p73 also contributes to differentiation particularly in neuronal cells where it promotes survival and development.

Pathways

The activity of p73 is involved in important signaling routes such as the DNA damage response and the apoptosis pathway. It interacts with many other proteins including p53 to maintain genomic stability. The pathway connections illustrate that p73 acts as a critical node influencing cell fate and maintaining cellular health.

Research links p73 to conditions such as cancer and neurodevelopmental disorders. Abnormal expression or mutation of p73 is observed in various cancers often associated with altered p53 function. In neurodevelopmental disorders deficits in p73 expression can impair brain development and function. Understanding how p73 interacts with p53 in these contexts is important for developing therapeutic strategies.

Target data

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).
