Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, respo ...
that in humans is encoded by the ''CEBPD''
gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a ba ...
.
Function
The protein encoded by this intronless gene is a bZIP transcription factor which can bind as a homodimer to certain DNA regulatory regions. It can also form heterodimers with the related protein CEBP-alpha. The encoded protein is important in the regulation of genes involved in immune and inflammatory responses, and may be involved in the regulation of genes associated with activation and/or differentiation of macrophages.
Functions
CEBPD is involved in regulation of apoptosis and cell proliferation. It probably acts as tumor suppressor.
One study in mice showed that CEBPD prevents development of tubular injury and tubulointerstitial fibrogenesis during the progression of chronic obstructive nephropathy.
Function of CEBPD gene can be effectively examined by siRNA knockdown based on an independent validation.
