General description

Dcp1 colocalizes with Dcp2 in distinct cytoplasmic foci along with other proteins involved in the 5′ to 3′ mRNA decay. These foci are termed PB (processing bodies) or DCP-bodies. DCP1A and DCP1B are the two distinct genes of human DCP1. They share ~70% homology in their N-termini and ~30% homology in their full length.

Human cells consists of two decapping protein 1a (DCP1a) homologues, hDcp1a and hDcp1b, that are coded by two distinct genes.

Application

Anti-DCP1A (N-terminal) antibody produced in rabbit has been used in:

immunoblotting
immunofluorescence
immunoprecipitation

Biochem/physiol Actions

Dcp1 cleaves the m7G mRNA cap in the 5′ to 3′ mRNA decay pathway. Decapping is a critical and highly regulated step in the turnover of mRNA which involves decapping enzymes that hydrolyze the cap structure at the 5′ mRNA.

Human decapping protein 1a (hDCP1a) acts as a processing body (PB) marker.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Identification of a human decapping complex associated with hUpf proteins in nonsense-mediated decay.

Jens Lykke-Andersen

Molecular and cellular biology, 22(23), 8114-8121 (2002-11-06)

Decapping is a key step in general and regulated mRNA decay. In Saccharomyces cerevisiae it constitutes a rate-limiting step in the nonsense-mediated decay pathway that rids cells of mRNAs containing premature termination codons. Here two human decapping enzymes are identified

RNA decapping inside and outside of processing bodies.

Christy Fillman et al.

Current opinion in cell biology, 17(3), 326-331 (2005-05-20)

Decapping is a central step in eukaryotic mRNA turnover. Recent studies have identified several factors involved in catalysis and regulation of decapping. These include the following: an mRNA decapping complex containing the proteins Dcp1 and Dcp2; a nucleolar decapping enzyme

The P body protein Dcp1a is hyper-phosphorylated during mitosis.

Adva Aizer et al.

PloS one, 8(1), e49783-e49783 (2013-01-10)

Processing bodies (PBs) are non-membranous cytoplasmic structures found in all eukaryotes. Many of their components such as the Dcp1 and Dcp2 proteins are highly conserved. Using live-cell imaging we found that PB structures disassembled as cells prepared for cell division

Multiple processing body factors and the ARE binding protein TTP activate mRNA decapping.

Martin Fenger-Grøn et al.

Molecular cell, 20(6), 905-915 (2005-12-21)

Decapping is a key step in mRNA turnover. However, the composition and regulation of the human decapping complex is poorly understood. Here, we identify three proteins that exist in complex with the decapping enzyme subunits hDcp2 and hDcp1: hEdc3, Rck/p54
