Recombinant Human Krueppel-like factor 4 (KLF4)

Uniprot Id

O43474

Target Species

Human

Target Name

KLF4

Target Full Name

Krueppel-like factor 4

Target Function

Transcription factor; can act both as activator and as repressor. Binds the 5'-CACCC-3' core sequence. Binds to the promoter region of its own gene and can activate its own transcription. Regulates the expression of key transcription factors during embryonic development. Plays an important role in maintaining embryonic stem cells, and in preventing their differentiation. Required for establishing the barrier function of the skin and for postnatal maturation and maintenance of the ocular surface. Involved in the differentiation of epithelial cells and may also function in skeletal and kidney development. Contributes to the down-regulation of p53/TP53 transcription.

Target Subcellular Location

Nucleus.

Target Protein Families

Krueppel C2H2-type zinc-finger protein family

Endothelial Kruppel like zinc finger protein ; Epithelial zinc finger protein EZF; EZF; GKLF; gut Kruppel-like factor; Gut-enriched krueppel-like factor; KLF; KLF4; KLF4_HUMAN; Krueppel-like factor 4; Kruppel like factor 4 (Epithelial zinc finger protein EZF) (Gut enriched Krueppel like factor); Kruppel like factor 4 (gut)

Target Background

This gene encodes a protein that belongs to the Kruppel family of transcription factors. The encoded zinc finger protein is required for normal development of the barrier function of skin. The encoded protein is thought to control the G1-to-S transition of the cell cycle following DNA damage by mediating the tumor suppressor gene p53. Mice lacking this gene have a normal appearance but lose weight rapidly, and die shortly after birth due to fluid evaporation resulting from compromised epidermal barrier function. Alternative splicing results in multiple transcript variants encoding different isoforms.
