Western blot - Anti-PHAP1 antibody (AB5992)

False colour image of Western blot : Anti-PHAP1 antibody staining at 0.5 ug/ml, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab5992 was shown to bind specifically to PHAP1. A band was observed at 33 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in ANP32A knockout cell line ab266148 (knockout cell lysate ab258303). To generate this image, wild-type and ANP32A knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween� 20 (TBS-T) before incubation with primary antibodies overnight at 4 �C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye� 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye� 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Product details

Apoptosis is related to many diseases and development. Caspase-9 plays a central role in cell death induced by a variety of apoptosis activators. Cytochrome c, after released from mitochondria, binds to Apaf-1, which forms an apoptosome that in turn binds to and activate procaspase-9. Activated caspase-9 cleaves and activates the effector caspases (caspase-3, -6 and –7), which are responsible for the proteolytic cleavage of many key proteins in apoptosis. The tumor suppressor putative HLA-DR-associated proteins (PHAPs) were recently identified as important regulators of mitochondrion apoptosis. PHAP appears to facilitate apoptosome-mediated caspase-9 activation and to stimulate the mitochondrial apoptotic pathway. PHAP was also shown to oppose both Ras- and Myc-mediated cell transformation.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

PHAP1 also known as putative HLA-associated protein 1 or ANP32A is a multifunctional phosphoprotein with a molecular weight of approximately 32 kDa. It exists within the nucleus and cytoplasm indicating its role in various cellular processes. PHAP1 expression is found across diverse tissues showing its widespread functional requirements in different biological contexts.
Biological function summary

PHAP1 plays an important role in regulating apoptosis and cell proliferation. It interacts with components of the INHAT complex which inhibits histone acetylation impacting chromatin remodeling and gene expression. By doing so it influences many cellular events such as cell cycle progression and differentiation. PHAP1's involvement in regulating cell death makes it a target for studying mechanisms underlying cell survival.

Pathways

PHAP1 is associated with apoptosis and cell signaling processes. It is intricately linked with the p38 MAPK signaling pathway important in stress response and inflammation. In these contexts PHAP1 interacts with proteins such as caspases and protein phosphatase 2A which are important for cellular responses to external and internal stimuli.

PHAP1 shows connections with cancer and neurodegenerative diseases. Altered expression levels of PHAP1 have been observed in certain types of cancers possibly affecting tumor growth and treatment responses. In neurodegeneration relations have been reported with tau proteins suggesting PHAP1's role in tauopathies potentially influencing disease progression and providing insights into therapeutic targets.

Target data

Multifunctional protein that is involved in the regulation of many processes including tumor suppression, apoptosis, cell cycle progression or transcription (PubMed : 10400610, PubMed : 11360199, PubMed : 16341127, PubMed : 18439902). Promotes apoptosis by favouring the activation of caspase-9/CASP9 and allowing apoptosome formation (PubMed : 18439902). In addition, plays a role in the modulation of histone acetylation and transcription as part of the INHAT (inhibitor of histone acetyltransferases) complex. Inhibits the histone-acetyltranferase activity of EP300/CREBBP (CREB-binding protein) and EP300/CREBBP-associated factor by histone masking (PubMed : 11830591). Preferentially binds to unmodified histone H3 and sterically inhibiting its acetylation and phosphorylation leading to cell growth inhibition (PubMed : 16341127). Participates in other biochemical processes such as regulation of mRNA nuclear-to-cytoplasmic translocation and stability by its association with ELAVL1 (Hu-antigen R) (PubMed : 18180367). Plays a role in E4F1-mediated transcriptional repression as well as inhibition of protein phosphatase 2A (PubMed : 15642345, PubMed : 17557114).. (Microbial infection) Plays an essential role in influenza A, B and C viral genome replication (PubMed : 30666459, PubMed : 32694517, PubMed : 33045004, PubMed : 33208942). Mechanistically, mediates the assembly of the viral replicase asymmetric dimers composed of PB1, PB2 and PA via its N-terminal region (PubMed : 33208942). Also plays an essential role in foamy virus mRNA export from the nucleus (PubMed : 21159877).
