KLF14

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

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

KLF14 appears to be a is_associated_with::master regulator of gene expression in is_associated_with::adipose tissue.

Protein structure
Like the other members of the KLF family, KLF14 has three zinc-finger domains near the is_associated_with::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.

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

Clinical significance
There appears to be a connection between KLF14 and is_associated_with::coronary artery disease, is_associated_with::hypercholesterolemia and is_associated_with::type 2 diabetes.
