STARD10 Overexpression Lysate Summary

• Description:

  STARD10 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC203228
  
  Accession#: NM_006645
  
  Protein Tag: C-MYC/DDK
  
  You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.
• Gene: STARD10

Applications/Dilutions

• Dilutions:
  • Western Blot
• Application Notes: This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.
  
  Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
• Theoretical MW: 32.9 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

• Storage: Store at -80C. Avoid freeze-thaw cycles.
• Buffer: RIPA buffer

Lysate Details for Array

• Type: Overexpression

Notes

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Background

STARD10, STAR-related lipid transfer protein 10 or PCTP-like (33 kDa) is a transporter for lipids which specifically shuttles phosphatidylcholine and phosphatidylethanolamine between membranes. Mammalian STARD10 belongs to a family of fifteen START-domain proteins. In these family members, the carboxy terminal START-domain is conserved and functions in lipid binding or as a lipid sensing domain. The specificity for the type of lipid bound differs among family members (e.g., STARD1,3,5 binds Cholesterol, STARD5 binds 25-hydroxycholesterol, STARD2 binds phosphatidylcholine, and STARD11 binds ceramides). STARD proteins have been associated with various cellular processes such as lipid trafficking, lipid metabolism, and cell signaling (1, 2).

STARD10 is broadly expressed in different organs and tissues such as the brain, endocrine tissues, liver, and gastrointestinal tract. STARD10 is regulated by Casein kinase II, which phosphorylates STARD10 at serine 284 leading to decreased lipid transfer activity and reduced membrane association. STARD10 is overexpressed in breast carcinoma cell lines and in primary breast cancers (3). STARD10 has been implicated in the regulation of bile acid homeostasis and more recently in the regulation of insulin secretion from beta-cells (1, 2, 4).
