HTT-GRK4 Fusion FISH Probe
The HTT-GRK4 Fusion FISH Probe is used to confirm a fusion of the HTT and GRK4 genes. The fusion of the HTT and GRK4 genes has been associated with Lung Squamous Cell Carcinoma, and Bladder Urothelial Carcinoma. These probes are FISH confirmed on normal peripheral blood in both interphase nuclei and metaphase spreads before shipment. Typical turnaround time for this product is 7-14 days after purchase.
** This product is for in vitro and research use only. This product is not intended for diagnostic use. Please note that both genes fall on the same chromosome and inter-chromosomal detection may be difficult to detect depending on the genes proximity to one another. Please consult our support staff before ordering this product to ensure that the probe can be designed to meet your specific needs.

GRK4 Gene Summary
This gene encodes a member of the guanine nucleotide-binding protein (G protein)-coupled receptor kinase subfamily of the Ser/Thr protein kinase family. The protein phosphorylates the activated forms of G protein-coupled receptors thus initiating its deactivation. This gene has been linked to both genetic and acquired hypertension. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2013]
Gene Name: G Protein-coupled Receptor Kinase 4
Chromosome: CHR4: 2965342 -3042474
Locus: 4p16.3
HTT Gene Summary
Huntingtin is a disease gene linked to Huntington's disease, a neurodegenerative disorder characterized by loss of striatal neurons. This is thought to be caused by an expanded, unstable trinucleotide repeat in the huntingtin gene, which translates as a polyglutamine repeat in the protein product. A fairly broad range of trinucleotide repeats (9-35) has been identified in normal controls, and repeat numbers in excess of 40 have been described as pathological. The huntingtin locus is large, spanning 180 kb and consisting of 67 exons. The huntingtin gene is widely expressed and is required for normal development. It is expressed as 2 alternatively polyadenylated forms displaying different relative abundance in various fetal and adult tissues. The larger transcript is approximately 13.7 kb and is expressed predominantly in adult and fetal brain whereas the smaller transcript of approximately 10.3 kb is more widely expressed. The genetic defect leading to Huntington's disease may not necessarily eliminate transcription, but may confer a new property on the mRNA or alter the function of the protein. One candidate is the huntingtin-associated protein-1, highly expressed in brain, which has increased affinity for huntingtin protein with expanded polyglutamine repeats. This gene contains an upstream open reading frame in the 5' UTR that inhibits expression of the huntingtin gene product through translational repression. [provided by RefSeq, Jul 2016]
