Product overview
Abcam’s knockout cell pellets give you access to native proteins, without the need to culture cells. Our knockout cell pellets are prepared from our single-gene knockout cell lines and provide an additional offering to our cell lysates.
Cells are snap-frozen to provide high quality pellets that are suitable for extraction with alternative lysis buffers or for preparation of lysates from subcellular fractions. Our knockout cell pellets are suitable for a variety of applications, including PCR, gene expression profiling and DNA library preparation. -

Function
Sequence-specific DNA-binding protein that interacts with inducible viral and cellular enhancer elements to regulate transcription of selected genes. AP-2 factors bind to the consensus sequence 5'-GCCNNNGGC-3' and activate genes involved in a large spectrum of important biological functions including proper eye, face, body wall, limb and neural tube development. They also suppress a number of genes including MCAM/MUC18, C/EBP alpha and MYC. AP-2-alpha is the only AP-2 protein required for early morphogenesis of the lens vesicle. -
Involvement in disease
Defects in TFAP2A are the cause of branchiooculofacial syndrome (BOFS) [MIM:113620]; also known as branchial clefts with characteristic facies, growth retardation, imperforate nasolacrimal duct, and premature aging or lip pseudocleft-hemangiomatous branchial cyst syndrome. BOFS is a rare autosomal dominant cleft palate craniofacial disorder with variable expressivity. The major features include cutaneous anomalies, ocular anomalies, characteristic facial appearance (malformed pinnae, oral clefts), and, less commonly, renal and ectodermal (dental and hair) anomalies. -
Sequence similarities
Belongs to the AP-2 family. -
Domain
The WW-binding motif mediates interaction with WWOX. -
Post-translational
modificationsSumoylated on Lys-10; which inhibits transcriptional activity. -

Western blot - Human TFAP2A (Transcription factor AP-2-alpha) knockout HeLa cell pellet (ab278855)Lane 1: Wild-type HeLa cell lysate (20µg)
Lane 2: TFAP2A knockout HeLa cell lysate (20µg)
Lanes 1- 2: Merged signal (red and green). Green - ab108311 observed at 48 kDa. Red - loading control, ab8245 observed at 37 kDa.
ab108311 Anti-Transcription factor AP-2-alpha antibody [EPR2688(2)] was shown to specifically react with Transcription factor AP-2-alpha in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265122 (knockout cell lysate ab257736) was used. Wild-type and Transcription factor AP-2-alpha knockout samples were subjected to SDS-PAGE. ab108311 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging. -
