Recombinant Human Krueppel-like factor 15 (KLF15)

Uniprot Id

Q9UIH9

Target Species

Human

Target Name

KLF15

Target Full Name

Krueppel-like factor 15

Target Function

Transcriptional regulator that binds to the GA element of the CLCNKA promoter. Binds to the KCNIP2 promoter and regulates KCNIP2 circadian expression in the heart. Is a repressor of CCN2 expression, involved in the control of cardiac fibrosis. It is also involved in the control of cardiac hypertrophy acting through the inhibition of MEF2A and GATA4. Involved in podocyte differentiation. Inhibits MYOCD activity. Is a negative regulator of TP53 acetylation. Inhibits NF-kappa-B activation through repression of EP300-dependent RELA acetylation.

Target Involvement

KLF15 deficiency results in loss of rhythmic QT variation and abnormal heart repolarization (PubMed:22367544). It may play a role in susceptibility to ventricular arrhythmias (PubMed:22367544), and development of pathological cardiac hypertrophy leading to heart failure (PubMed:20375365).

Target Subcellular Location

Nucleus.

Target Protein Families

Sp1 C2H2-type zinc-finger protein family

Target Tissue Specificity

Highly expressed in liver, skeletal muscle, and kidney. Expressed in cardiomyocytes. Expression is highly reduced in cardiac tissue of patients with non-ischemic cardiomyopathy and aortic aneurysm, and in glomerular disease. Not expressed in bone marrow o

Target Background

Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in negative regulation of peptidyl-lysine acetylation and positive regulation of transcription by RNA polymerase II. Located in nuclear speck.
