Applications and conditions

Where to start

These starting conditions come from the recommended dilution, validation images, and general assay practice. Titrate for your sample and detection system.

WB Conditions for WB
Recommended dilution 1:500 - 1:1000
Suggested sample / positive control U-87MG
Key conditions Use a fresh lysate, incubate at the recommended dilution, and check the predicted and observed molecular weight
Expected result Expected signal or band near 90KDa
Controls Include a positive sample, a negative sample, and a secondary or isotype control
IF/ICC Conditions for IF/ICC
Recommended dilution 1:50 - 1:200
Suggested sample / positive control U-87MG
Key conditions Optimize fixation, permeabilization, and blocking, and include a secondary-only control
Expected result Expected fluorescence localization: cytoplasm,cytoplasmic vesicle,cytosol,lysosome,melanosome
Controls Include a positive sample, a negative sample, and a secondary or isotype control

Target data

Background This gene encodes a protein component of biogenesis of lysosome-related organelles complexes (BLOC). BLOC complexes are important for the formation of endosomal-lysosomal organelles such as melanosomes and platelet dense granules. Mutations in this gene result in subtype 4 of Hermansky-Pudlak syndrome, a form of albinism. Alternative splicing results in multiple transcript variants.
Gene ID 89781
Gene name HPS4
Swiss Q9NQG7
Synonym HPS4,BLOC3S2,LE,HPS4 Rabbit pAb,Hermansky-Pudlak syndrome 4 protein,Light-ear protein homolog,KIAA1667
Functions Component of the BLOC-3 complex, a complex that acts as a guanine exchange factor (GEF) for RAB32 and RAB38, promotes the exchange of GDP to GTP, converting them from an inactive GDP-bound form into an active GTP-bound form. The BLOC-3 complex plays an important role in the control of melanin production and melanosome biogenesis and promotes the membrane localization of RAB32 and RAB38 (PubMed:23084991).
