機能
Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facilitates the passage of RNA polymerase II and transcription by promoting the dissociation of one histone H2A-H2B dimer from the nucleosome, then subsequently promotes the reestablishment of the nucleosome following the passage of RNA polymerase II. The FACT complex is probably also involved in phosphorylation of 'Ser-392' of p53/TP53 via its association with CK2 (casein kinase II). Binds specifically to double-stranded DNA and at low levels to DNA modified by the antitumor agent cisplatin. May potentiate cisplatin-induced cell death by blocking replication and repair of modified DNA. Also acts as a transcriptional coactivator for p63/TP63. -
配列類似性
Belongs to the SSRP1 family.
Contains 1 HMG box DNA-binding domain. -
ドメイン
The HMG box DNA-binding domain mediates DNA-binding. It has both affinity and specificity for DNA damaged globally with cisplatin. -
翻訳後修飾
Phosphorylated by CK2 following UV but not gamma irradiation. Phosphorylation inhibits its DNA-binding activity.
Ubiquitinated. Polyubiquitinated following caspase cleavage resulting in degradation of the N-terminal ubiquitinated part of the cleaved protein.
Sumoylated. -
細胞内局在
Nucleus. Chromosome. Colocalizes with RNA polymerase II on chromatin. Recruited to actively transcribed loci. - Information by UniProt

All lanes : Anti-SSRP1 antibody (ab21584) at 1/500 dilution
Lane 1 : U2OS cell lysate
Lane 2 : U2OS cell lysate treated with ionizing radiation
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 81 kDa
Observed band size: 90 kDa why is the actual band size different from the predicted?
Additional bands at: 70 kDa (possible cleavage fragment), 70 kDa (possible cross reactivity)
From a 60 mm dish, cells were scraped into 75 ul of 2X laemmli buffer and 20ul was loaded onto the SDS-PAGE gel. ab21584 recognizes a protein at approximately 90 kDa which corresponds closely to the size of SSRP1. -
ICC/IF image of ab21584 stained human HEK 293 cells. The cells were methanol fixed (5 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab21584, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HeLa, HepG2 and MCF7 cells.
