The GANP Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect GANP protein expression profile in cells. The kit can be used for measuring the relative amounts of GANP in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on GANP.

Qualitative determination of GANP concentration is achieved by an indirect ELISA format. In essence, GANP is captured by GANP-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:

1. A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values.
2. Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted.

Sub Type:None
UniProt Protein Function:GANP: is a member of the SAC3 family of nuclear export factors. In combination with ENY2, PCID2 and centrins, forms the TREX-2 complex that links transcription/ processing with nuclear mRNA export. GANP, required to recruit ENY2 to nuclear pore complexes (NPCs), requires both its CID and MCM3AP domains, together with nucleoporin Nup153, for recruitment to NPCs. The MCM3AP domain, corresponding to the carboxy-terminal 721 amino acids of GANP, shows homology with the Gcn5-related N acetyltransferase superfamily. The protein MCM3AP is encoded entirely within the 3¿ region of the GANP gene. MCM3AP transcription begins within intron 16 of GANP immediately upstream of the first MCM3AP exon, where NF-IL6, AP-1, NF-¿B, and p53 consensus transcription factor binding sites are located. In contrast, the GANP promoter region contains consensus transcription factor binding sites for E2F, E-box, BSAP, and PU.1. MCM3AP interacts with MCM3, which it can acetylate weakly in vivo. GANP is required for efficient mRNA nuclear export: GANP depletion results in the nuclear accumulation of poly(A)+RNA. It interacts via its N-terminal FG repeat domain with the mRNA export factor NXF1. GANP plays a role in the immune response: antibodies from mice deficient for GANP have reduced affinities against T-cell dependent antigens and a lower frequency of variable region somatic mutation. GANP expression is markedly decreased in malignant glioma (MG) with a poor prognosis, consistently lower than that observed in anaplastic astrocytomas. Significant decreases in GANP expression are associated with hyperploidy and chromosomal instability

NCBI Summary:The minichromosome maintenance protein 3 (MCM3) is one of the MCM proteins essential for the initiation of DNA replication. The protein encoded by this gene is a MCM3 binding protein. It was reported to have phosphorylation-dependent DNA-primase activity, which was up-regulated in antigen immunization induced germinal center. This protein was demonstrated to be an acetyltransferase that acetylates MCM3 and plays a role in DNA replication. The mutagenesis of a nuclear localization signal of MCM3 affects the binding of this protein with MCM3, suggesting that this protein may also facilitate MCM3 nuclear localization. This gene is expressed in the brain or in neuronal tissue. An allelic variant encoding amino acid Lys at 915, instead of conserved Glu, has been identified in patients with mild intellectual disability. [provided by RefSeq, Jan 2014]
