KLF14

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.^[5] The corresponding Klf14 mouse gene is known as Sp6.^[6]

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).^[7] KLF14 is expressed in many tissues,^[8] lacks introns, and is subject to parent-specific expression.^[9]

KLF14 appears to be a master regulator of gene expression in adipose tissue.^[10]

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.^[11]

Human KLF14 is 323 amino acids in length, with a molecular weight of 33,124;^[11] in the mouse its length is 325.^[12]

Clinical significance

There appears to be a connection between KLF14 and coronary artery disease, hypercholesterolemia and type 2 diabetes.^[13][14]
