Genomic Imprinting
BACKGROUND Genomic imprinting is the inheritance out of Mendelian borders. Many of inherited diseases and human development violates Mendelian law of inheritance, this way of inheriting is studied by epigenetics. AIM The aim of this review is to analyze current opinions and options regarding to this way of inheriting. RESULTS Epigenetics shows that gene expression undergoes changes more com...
متن کاملGenomic imprinting
Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed. If the allele from the mother is imprinted, then only the allele from the father is expressed. Forms of genomic imprinting have been demonstrated...
متن کاملGenomic imprinting
Genomic imprinting is a normal form of gene regulation that causes a subset of mammalian genes to be expressed from one of the two parental chromosomes. Some imprinted genes are expressed from the maternally inherited chromosomes and others from the paternally inherited chromosomes. This means that the maternal and paternal genomes are not functionally equivalent and is the reason why both a ma...

Arabidopsis thaliana carboxyl-terminal domain (CTD) phosphatase-like 1 (CPL1) is a protein that regulates plant transcriptional responses to diverse stress signals. Unlike prototypical CTD phosphatases, which contain a phospho-peptide-binding Breast Cancer 1 C-terminal (BRCT) domain, CPL1 contains 2 double-stranded RNA binding motifs (dsRBM) at its C-terminus. While some dsRBMs can bind to dsRN...
متن کاملMechanisms of genomic imprinting.
Imprinted genes represent a curious defiance of normal Mendelian genetics. Mammals inherit two complete sets of chromosomes, one from the mother and one from the father, and most autosomal genes will be expressed from both the maternal and the paternal alleles. Imprinted genes, however, are expressed from only one chromosome, in a parent-of-origin-dependent manner. Because silent and active pro...
