功能
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. -
组织特异性
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. -
序列相似性
Belongs to the p53 family.
Contains 1 SAM (sterile alpha motif) domain. -
结构域
Possesses an acidic transactivation domain, a central DNA binding domain and a C-terminal oligomerization domain that binds to the ABL tyrosine kinase SH3 domain.
The WW-binding motif mediates interaction with WWOX. -
翻译后修饰
Isoform alpha (but not isoform beta) is sumoylated on Lys-627, which potentiates proteasomal degradation but does not affect transcriptional activity.
Higher levels of phosphorylation seen in the brain from patients with Huntington disease.
Ubiquitinated; leading to its degradation by the proteasome. -
细胞定位
Nucleus. Accumulates in the nucleus in response to DNA damage. - Information by UniProt

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: p73 knockout HAP1 whole cell lysate (20 µg)Lanes 1 - 2: Merged signal (red and green). Green - ab202474 observed at 75 kDa. Red - loading control, ab9484, observed at 37 kDa.
ab202474 was shown to recognize p73 in wild-type HAP1 cells as signal was lost at the expected MW in p73 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and p73 knockout samples were subjected to SDS-PAGE. Ab202474 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

p73 was immunoprecipitated from 0.35mg of HepG2 (Human liver hepatocellular carcinoma cell line) whole cell lysate with ab202474 at 1/40 dilution. Western blot was performed from the immunoprecipitate using ab202474 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

Lane 2: ab202474 IP in HepG2 whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab202474 in HepG2 whole cell lysate.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.

Chromatin was prepared from HCT 116 (Human colorectal carcinoma cell line) cells treated with 1mM Hydroxyurea for 16h and non-treated according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 2µg of ab202474 (blue), and 20µl of Anti rabbit IgG sepharose beads. 2μg of rabbit normal IgG was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).
