  • Function

    Nicotinic acid adenine dinucleotide phosphate (NAADP) receptor that may function as one of the major voltage-gated Ca(2+) channels (VDCC) across the lysosomal membrane. May be involved in smooth muscle contraction.
  • Tissue specificity

    Widely expressed. Expressed at high level in liver and kidney.
  • Sequence similarities

    Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family. Two pore calcium channel subfamily.
  • Domain

    Each of the two internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position.
  • Post-translational

  • Cellular localization

    Lysosome membrane. Only the acidic lysosomal fraction is sensitive to NAADP.

Thank you for your reply and for kindly providing the image again which I have been able to access.

I see there is one clear single band in the sample lane on the blot. Because of the image quality, and because some of the bands are very faint, I am not completely sure which band in the molecular weight markers relates to which size. What size would you say the sample band is at? Because some of the marker bands are extremely faint, I am not sure if perhaps some of the smaller markers bands have run off the gel and therefore the sample band may be at the correct size?

Thank you for your cooperation. I would appreciate if you could provide further information.
