HAP1 antibody - 100 µg
Host : Rabbit
Clonality: Polyclonal
Clone:
Isotype: IgG
Immunogen: huntingtin-associated protein 1
Purity: ≥95% as determined by SDS-PAGE
Form: Liquid
Molecular weight: 75-80 kDa
Uniprot: P54257
Gene id: 9001
Background: Originally identified as neuronal protein that specifically associates with HTT
huntingtin and the binding is enhanced by an expanded polyglutamine repeat within HTT possibly affecting HAP1 interaction properties. Both HTT and HAP1 are involved in intracellular trafficking and HAP1 is proposed to link HTT to motor proteins and
or transport cargos. Seems to play a role in vesicular transport within neurons and axons such as from early endosomes to late endocytic compartments and to promote neurite outgrowth. The vesicular transport function via association with microtubule-dependent transporters can be attenuated by association with mutant HTT. Involved in the axonal transport of BDNF and its activity-dependent secretion; the function seems to involve HTT, DCTN1 and a complex with SORT1. Involved in APP trafficking and seems to faciltate APP anterograde transport and membrane insertion thereby possibly reducing processing into amyloid beta. Involved in delivery of gamma-aminobutyric acid(GABA(A)) receptors to synapses; the function is dependent on kinesin motor protein KIF5 and is disrupted by HTT with expanded polyglutamine repeat. Involved in regulation of autophagosome motility by promoting efficient retrograde axonal transport. Seems to be involved in regulation of membrane receptor recycling and degradation, and respective signal transduction, including GABA(A) receptors, tyrosine kinase receptors, EGFR, IP3 receptor and androgen receptor. Among others suggested to be involved in control of feeding behavior(involving hypothalamic GABA(A) receptors), cerebellar and brainstem development(involving AHI1 and NTRK1
TrkA), postnatal neurogenesis(involving hypothalamic NTRK2
TrkB), and ITPR1
InsP3R1-mediated Ca(2+) release(involving HTT and possibly the effect of mutant HTT). Via association with DCTN1
dynactin p150-glued and HTT
huntingtin involved in cytoplasmic retention of REST in neurons. May be involved in ciliogenesis. Involved in regulation of exocytosis. Seems to be involved in formation of cytoplasmic inclusion bodies(STBs). In case of anomalous expression of TBP, can sequester a subset of TBP into STBs; sequestration is enhanced by an expanded polyglutamine repeat within TBP. HAP1-containing STBs have been proposed to play a protective role against neurodegeneration in Huntigton disease(HD) and spinocerebellar ataxia 17(SCA17).
