Our Abpromise guarantee covers the use of ab2905 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000. Detects a band of approximately 305 kDa (predicted molecular weight: 309 kDa). (in lysate from UV irradiated K562 cells).|
功能Serine/threonine protein kinase which activates checkpoint signaling upon genotoxic stresses such as ionizing radiation (IR), ultraviolet light (UV), or DNA replication stalling, thereby acting as a DNA damage sensor. Recognizes the substrate consensus sequence [ST]-Q. Phosphorylates BRCA1, CHEK1, MCM2, RAD17, RPA2, SMC1 and p53/TP53, which collectively inhibit DNA replication and mitosis and promote DNA repair, recombination and apoptosis. Phosphorylates 'Ser-139' of histone variant H2AX/H2AFX at sites of DNA damage, thereby regulating DNA damage response mechanism. Required for FANCD2 ubiquitination. Critical for maintenance of fragile site stability and efficient regulation of centrosome duplication.
组织特异性Ubiquitous, with highest expression in testis. Isoform 2 is found in pancreas, placenta and liver but not in heart, testis and ovary.
疾病相关Defects in ATR are a cause of Seckel syndrome type 1 (SCKL1) [MIM:210600]. SCKL1 is a rare autosomal recessive disorder characterized by growth retardation, microcephaly with mental retardation, and a characteristic 'bird-headed' facial appearance.
序列相似性Belongs to the PI3/PI4-kinase family. ATM subfamily.
Contains 1 FAT domain.
Contains 1 FATC domain.
Contains 2 HEAT repeats.
Contains 1 PI3K/PI4K domain.
翻译后修饰Phosphorylated; autophosphorylates in vitro.
细胞定位Nucleus. Nucleus > PML body. Depending on the cell type, it can also be found in PML nuclear bodies. Recruited to chromatin during S-phase. Redistributes to discrete nuclear foci upon DNA damage, hypoxia or replication fork stalling.

Western blot on ATR in K562 whole cell lysate using ab2905.
All lanes : Anti-ATR antibody (ab2905) at 1/1000 dilution
Lane 1 : MCF10A breast epithelial cells, grown in normoxic conditions (20% O2). Cells were lysed with NP40.
Lane 2 : MCF10A Breast Epithelial cells grown in hypoxic. conditions (5% O2). Cells were lysed with NP40.
Lysates/proteins at 10 µg per lane.
All lanes : Goat anti Rabbit (HRP) at 1/10000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 309 kDa
Observed band size: 300 kDa why is the actual band size different from the predicted?
Exposure time: 30 seconds
Blocking: Carried out using non fat dry milk for 1 hr at room temperature.
