Target description

Zinc finger protein GLI2 (UniProt: P10070; also known as GLI family zinc finger protein 2, Tax helper protein) is encoded by the Gli2 (also known as THP) gene (Gene ID: 2736) in human. In vertebrates three Gli proteins (Gli-1, Gli-2, and Gli-3) have been described that despite the presence of several homologous regions, including a DNA-binding domain with five C2-H2 zinc fingers and a C-terminal transcription activation domain, have distinct activities and are not considered to be functionally equivalent. Gli-1 and Gli-2 function primarily as activators whereas Gli-3 has a repressor role. Gli-2 contains five C3H2-type zinc fingers. Its N-terminal domain confers transcriptional repressor activity, while the C-terminal domain mediates transcriptional activation. Transcriptional activity of Gli proteins is also regulated through its binding to Suppressor of Fu (Sufu), which is a negative regulator of Hedgehog signaling in Drosophila as well as in vertebrates. Sufu binds to all three Gli proteins with different affinities. Phosphorylation of Gli-2 by DYRK2 is shown to block its transcriptional activity and promotes its proteasomal degradation. Gli-2 is reported to be essential for normal embryonic development. Gli-2 affects ventroposterior mesodermal development through its regulation of Wnt, Brachyury and Xhox3 gene families. Knockout studies have shown that Gli-1 can compensate for Gli-2, but replacement is not perfect and is context dependent. Gli-2 null mice embryos develop neural tube defects and double knockout Gli1 and Gli-2 mice display serious central nervous system and lung defects. Overexpression of Gli-2 has been linked to tumorigenesis and can lead to basal cell carcinomas. Mutations in Gli-2 gene have been linked to holoprosencephaly 9 that is characterized by failure of forebrain to correctly separate into right and left hemispheres. Gli-2 gene mutations are also known to cause Culler-Jones syndrome that features pituitary dysfunction, syndactyly, hypothalamic hamartoma, and visceral malformations. Five isoforms of Gli-2 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

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.
