Kruppel-like factor 13, also known as KLF13, is a protein that in humans is encoded by the KLF13 gene.[3][4][5]

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.[6] Ghrelin levels also positively correlated with methylation levels of cg07814318.[6] Moreover, expression levels of KLF13 were decreased and increased in the brains of starved and obese mice, respectively.[6]


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.[3][7]

KLF13 was first described as the RANTES factor of late activated T lymphocytes (RFLAT)-1.[5] 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.[5][8][9][10][11][12][13]


KLF13 has been shown to interact with CREB-binding protein,[14] Heat shock protein 47[14] and PCAF.[14]
