  • Primary antibody notesPineal gland serotonin N-acetyltransferase (arylalkylamine N-acetyltransferase, AA-NAT) is an ~23 kDa protein which is the rate-limiting enzyme in melatonin synthesis. Melatonin serves as the hormonal signal of the daily light/dark cycle, or body clock. The nocturnal oscillation in enzyme activity ranges by 10- to 100-fold depending on species among vertebrates. Studies have shown that AA-NAT is regulated by cAMP at both the mRNA and protein levels. AA-NAT has putative protein kinase A (PKA) sites at Thr 29 and Ser 206. Phosphorylation of AA-NAT at these residues might play a role in protein inactivation via proteasome-dependent degradation.

Applications

Our Abpromise guarantee covers the use of ab3505 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 µg/ml. Detects a band of approximately 23 kDa (predicted molecular weight: 23 kDa).Can be blocked with Serotonin N-acetyltransferase peptide (ab5003).

This antibody detects an ~23 kDa protein representing unphosphorylated and phosphorylated AA-NAT from rat pineal gland whole protein extract.

IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

Target

  • FunctionControls the night/day rhythm of melatonin production in the pineal gland. Catalyzes the N-acetylation of serotonin into N-acetylserotonin, the penultimate step in the synthesis of melatonin.
  • Tissue specificityHighly expressed in pineal gland and at lower levels in the retina. Weak expression in several brain regions and in the pituitary gland.
  • PathwayAromatic compound metabolism; melatonin biosynthesis; melatonin from serotonin: step 1/2.
  • Involvement in diseaseDelayed sleep phase syndrome
  • Sequence similaritiesBelongs to the acetyltransferase family. AANAT subfamily.
    Contains 1 N-acetyltransferase domain.
  • Post-translational
    modifications
    cAMP-dependent phosphorylation on both N-terminal Thr-31 and C-terminal Ser-205 regulates AANAT activity by promoting interaction with 14-3-3 proteins.

Anti-Serotonin N-acetyltransferase antibody images

  • IHC image of Serotonin N-acetyltransferase staining in Rat brain formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab3505, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Regarding the feedback on the secondary and the loading control working well, this is very reassuring and tells us the problem is not due to these. As the customer is sure the cells she is investigating are still pineal and should definitely express Se...
