text: GLD-2 is a common and abundant, but yet quite unknown protein that has already been found in each of the five kingdoms. In the animal kingdom, it has been specially detected in Homo sapiens, Drosophila, Xenopus and Mus musculus. However, there has also been noticed the presence of GLD-2 in Arabidopsis thaliana which belongs in the plants kingdom; Escherichia Coli in monera and Candida albicans in fungi.
  In human beings it is mostly expressed in the brain and within it, in the cerebellum, hippocampus and medulla. We can also find them in some other source tissues are the fibroblast, HeLa cell, MCF-7 cell, melanoma cell line and thymus. Inside those cells, it can be located in the nucleus and mitochondrion since its main function is related with DNA polyadenilation and these cell organelles are the only ones were DNA can be found. However, there are also GLD-2 in a soluble way in the cytosol, although the reason why they are there is still unsure.
  In Escherichia Coli, this enzymatic protein can be found in the cell membrane and in the cytosol, whereas in Drosophila melanogaster, it predominates in the brains nucleus and cytoplasm, oocyte, ovary and testis’ cells. Finally, in the Arabidopsis thaliana, it is located in the flowers nucleus, root, stem and leaf cells.
