Krüppel-like factor 14, also known as basic transcription element-binding protein 5 (BTEB5) is a protein that in humans is encoded by the KLF14 gene.[3] The corresponding Klf14 mouse gene is known as Sp6.[4]

Function

KLF14 is a member of the Krüppel-like factor family of transcription factors. It regulates the transcription of various genes, including TGFβRII (the type II receptor for TGFβ).[5] KLF14 is expressed in many tissues,[6] lacks introns, and is subject to parent-specific expression.[7]

KLF14 appears to be a master regulator of gene expression in adipose tissue.[8]

Protein structure

Like the other members of the KLF family, KLF14 has three zinc-finger domains near the C-terminus, all three of which are of the classical C2H2 type. In the human, they are at amino acids 195–219, 225–249, and 255–277.[9]

Human KLF14 is 323 amino acids in length, with a molecular weight of 33,124;[9] in the mouse its length is 325.[10]

Clinical significance

There appears to be a connection between KLF14 and coronary artery disease, hypercholesterolemia and type 2 diabetes.[11][12]
