Applications
Our Abpromise guarantee covers the use of ab3517 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 |
|---|---|---|
| IHC-P | 1/100 - 1/1000. Immunohistochemical staining of CLOCK in hamster brain results in the staining of the superchiasmatic nucleus. |
|
| WB | 1/200. Detects a band of approximately 100 kDa (predicted molecular weight: 95 kDa). By Western blot, this antibody detects an ~100 kDa protein representing CLOCK from rat brain homogenate. |

Function
ARNTL/2-CLOCK heterodimers activate E-box element (3'-CACGTG-5') transcription of a number of proteins of the circadian clock. Activates transcription of PER1 and PER2. This transcription is inhibited in a feedback loop by PER and CRY proteins. Has intrinsic histone acetyltransferase activity and this enzymatic function contributes to chromatin-remodeling events implicated in circadian control of gene expression (By similarity). Acetylates primarily histones H3 and H4 (By similarity). Acetylates also a non-histone substrate: ARNTL. -
Tissue specificity
Expressed in all tissues examined including spleen, thymus, prostate, testis, ovary, small intestine, colon, leukocytes, heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Highest levels in testis and skeletal muscle. Low levels in thymus, lung and liver. Expressed in all brain regions with highest levels in cerebellum. Highly expressed in the suprachiasmatic nucleus (SCN). -
Sequence similarities
Contains 1 basic helix-loop-helix (bHLH) domain.
Contains 1 PAC (PAS-associated C-terminal) domain.
Contains 2 PAS (PER-ARNT-SIM) domains. -
Post-translational
modificationsPhosphorylation is dependent on CLOCK-ARNTL heterodimer formation. -
Cellular localization
Cytoplasm. Nucleus. Shuffling between the cytoplasm and the nucleus is under circadian regulation and is ARNTL-dependent. Phosphorylated form located in the nucleus. - Information by UniProt

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-KAT13D / CLOCK antibody (ab3517)ab3517 labelling KAT13D in the nucleus and cytoplasm of Mouse colon tissue (right) compared with a negative control (left) by Immunohistochemistry (formalin/PFA-fixed paraffin-embedded sections). To expose target proteins, antigen retrieval method was performed using 10mM sodium citrate (pH 6.0) microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature. Thissue sections were incubated with the primary antibody (1:200 in 3% BSA-PBS) overnight at 4°C. A HRP-conjugated anti-rabbit IgG was used as the secondary antibody, followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-KAT13D / CLOCK antibody (ab3517)This image is courtesy of an anonymous Abreviewab3517 staining KAT13D/CLOCK in Mouse skeletal muscle tissue sections by IHC-P (Paraformaldehyde-fixed, paraffin-embedded tissue sections). Tissue was fixed with paraformaldehyde and blocked with 10% serum for 1 hour at 20°C; antigen retrieval was by heat mediation in citrate buffer pH6. Samples were incubated with primary antibody (1/400 in PBS) for 12 hours at 4°C. Undiluted ab64256 was used as the secondary antibody. -

Performed under reducing conditions.
Predicted band size: 95 kDa
Observed band size: 95 kDa
Additional bands at: 105 kDa (possible post-translational modification), 38 kDa, 45 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 30 seconds
KAT13D / CLOCK contains a number of potential phosphorylation sites (SwissProt) which may explain the banding pattern observed at a higher molecular weight than predicted.
