Kruppel-like factor 13, also known as KLF13, is a protein that in humans is encoded by the KLF13 gene.[1][2][3]

There is some evidence for KLF13 having a role in obesity. A methylation site, cg07814318, within the first intron of KLF13 has been associated with obesity and orexigenic processes.[4] Ghrelin levels also positively correlated with methylation levels of cg07814318.[4] Moreover, expression levels of KLF13 were decreased and increased in the brains of starved and obese mice, respectively.[4]


KLF13 belongs to a family of transcription factors that contain 3 classical zinc finger DNA-binding domains consisting of a zinc atom tetrahedrally coordinated by 2 cysteines and 2 histidines (C2H2 motif). These transcription factors bind to GC-rich sequences and related GT and CACCC boxes.[1][5]

KLF13 was first described as the RANTES factor of late activated T lymphocytes (RFLAT)-1.[3] It regulates the expression of the chemokine RANTES in T lymphocytes. It functions as a lynchpin, inducing a large enhancesome. KLF13 knock-out mice show a defect in lymphocyte survival as KLF13 is a regulator of Bcl-xL expression.[3][6][7][8][9][10][11]


KLF13 has been shown to interact with CREB-binding protein,[12] Heat shock protein 47[12] and PCAF.[12]
