General description
Transcription cofactor vestigial-like protein 4 (UniProt: Q14135; also known as Vgl-4, VGLL4) is encoded by the VGLL4 (also known as KIAA0121) gene (Gene ID: 9686) in human. VGLL4 is a member of the vestigial like family that acts as a transcriptional cofactor of VGLL. It functions as a regulator of Wnt/β-catenin signaling. It negatively regulates Wnt/β-catenin signal transduction pathway via inhibiting β-catenin and TCF. It performs its biological functions through two TDU domains (aa 214-224 and 242-252) via interacting with TEA domain (TEAD) transcription factors. It is shown to be a transcriptional suppressor that inhibits YAP-induced overgrowth and tumorigenesis through direct competition with YAP for binding TEAD4. It binds to the TEAD4-TCF4 complex and inhibits transactivation of both TCF4 and TEAD4. Deletion of its second TDU domain (aa 242-252) is reported to completely abolished its inhibitory function. Lower expression VGLL4 is associated with poor survival in many human cancers. Its levels are shown to be significantly downregulated in colorectal cancers (CRC) and are inversely correlated with the expression of Wnt/β-catenin target genes. Knockdown of VGLL4 gene enhances proliferation and tumor formation of CRC cells. It is also reported to suppress epithelial-mesenchymal transition (EMT) and contribute to apoptosis signal transduction pathway. It can negatively regulate XIAP, cIAP1, and cIAP2 and contribute to apoptosis by forcing the nuclear relocation and sequestration of these proteins. VGLL4 is phosphorylated by CDK1 during G2/M arrest, which inhibits its tumor suppressing activity. This ZooMAbZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 1K23 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Transcription cofactor vestigial-like protein 4 (VGLL4).
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
