Metastatic lymph node 51 [MLN51 (also known as CASC3)] is a component of the exon junction complex (EJC), which is assembled on spliced mRNAs and plays important roles in post-splicing events. The four proteins of the EJC core, MLN51, MAGOH, Y14 and EIF4AIII shuttle between the cytoplasm and the nucleus. However, unlike the last three, MLN51 is mainly detected in the cytoplasm, suggesting that ...
Spermatogenesis in Marsilea vestita is a rapid process that is activated by placing dry microspores into water. Nine division cycles produce seven somatic cells and 32 spermatids, where size and position define identity. Spermatids undergo de novo formation of basal bodies in a particle known as a blepharoplast. We are interested in mechanisms responsible for spermatogenous initial formation. M...
Pre-mRNA splicing deposits multi-protein complexes, termed exon junction complexes (EJCs), on mRNAs near exon-exon junctions. The core of EJC consists of four proteins, eIF4AIII, MLN51, Y14 and Magoh. Y14 is a nuclear protein that can shuttle between the nucleus and the cytoplasm, and binds specifically to Magoh. Here we delineate a Y14 nuclear localization signal that also confers its nuclear ...
Hedgehog (Hh) regulates the Cubitus interruptus (Ci) transcription factor in Drosophila melanogaster by activating full-length Ci-155 and blocking processing to Ci-75 repressor. However, the interplay between regulation of Ci-155 levels and activity, as well as processing-independent mechanisms that affect Ci-155 levels have not been explored extensively. Here we identified Mago Nashi (Mago) an...
Acetyl-coenzyme A carboxylase α (ACC-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. ACC-alpha gene is located on Caprine chromosome 11 and is polymorphic in many goat breeds. In the current study, we aimed to find possible single nucleotide polymorphisms (SNPs) in the exon 1 region of the ACC-alpha gene in Iranian Mahabadi goat breed. Genomic DNA was extracted fro...
Background and Objectives: The neuromuscular degenerative disorder, known as spinal muscular atrophy (SMA), is a common fatal disease in neonates. In most patients with SMA, exon 7 and/or exon 8 of SMN1 gene is deleted. It is reported that the deletion of exon 5 from NAIP gene may be involved in the severity of SMA disease. The present study was aimed to evaluate the genotype- phenotype correla...
