Mol. Weight
29.7 kDa
Protein Length
Full Length of Mature Protein
Tag Info
N-terminal 10xHis-tagged and C-terminal Myc-tagged
Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Calcium-binding protein that may play a role in the regulation of voltage-dependent calcium channels. May also play a role in cyclic-nucleotide-mediated signaling through the regulation of adenylate and guanylate cyclases.
Gene References into Functions
  1. Sequence analysis of the HPCA gene in 505 patients with dystonia did not reveal variants in the coding regions of HPCA. PMID: 27145302
  2. hippocalcin forms oligomers upon calcium binding and directly interacts with VGCCs. The dystonia-causing mutations did not affect protein stability or folding. In common for both T71N and A190T mutants was an impaired calcium-dependent oligomerisation and increased intracellular calcium influx after KCl depolarisation. PMID: 28398555
  3. None of the patients enrolled was found to carry HPCA mutations, rising suspicion that these probably represent a very rare cause of dystonia in childhood-adolescence. PMID: 27771228
  4. Mutations in HPCA cause autosomal-recessive primary isolated dystonia. PMID: 25799108
  5. analysis of a novel acetylation cycle of transcription co-activator Yes-associated protein that is downstream of Hippo pathway is triggered in response to SN2 alkylating agents PMID: 22544757
  6. Hippocalcin is a sensitive Ca2+ sensor capable of responding to increases in intracellular Ca2+ concentration over the narrow dynamic range of 200-800 nM free Ca2+. PMID: 14638856
  7. The structural factors affecting the binding of hippocalcin to phosphatidylinositol 4,5-bisphosphate at the cell surface and the Golgi apparatus are described. PMID: 16053445
  8. Hippocalcin and MLK2 were colocalized in the halo of Lewy bodies in Parkinson disease patients, and neither protein was detected in normal pigmented neurons. PMID: 19332348
  9. diminished hippocalcin expression does not contribute to Huntington disease-related neurodegeneration PMID: 19686238
