The nuclear pore complex protein plays a role in bidirectional transport across the nucleoporin complex in nucleocytoplasmic transport. The mammalian nuclear pore complex (NPC) is comprised of approximately 30 unique proteins, collectively known as nucleoporins [2]. This entry includes yeast family members such as Nup145p as well as vertebrate Nup98. The NUP C-terminal domains of Nup98 and Nup145 possess peptidase S59 autoproteolytic activity. The autoproteolytic sites of Nup98 and Nup145 each occur immediately C-terminal to the NUP C-terminal domain. Thus, although this domain occurs in the middle of each precursor polypeptide, it winds up at the C-terminal end of the N-terminal cleavage product. Cleavage of the peptide chains are necessary for the proper targeting to the nuclear pore [3].

SPRY Domain is named from SPla and the RYanodine Receptor and it is found in many eukaryotic proteins with a wide range of functions. It is a protein-interaction module involved in many important signalling pathways like RNA processing, regulation of histone H3 methylation, innate immunity or embryonic development [1,2,3,4]. It can be divided into 11 subfamilies based on amino acid sequence similarity or the presence of additional protein domains. The greater SPRY family is divided into the SPRY/B30.2 (which contains a PRY extension at the N-terminal) and SPRY-only sub-families which are preceded by a subdomain that is structurally similar to the PRY region [2]. SPRY/B30.2 structures revealed a bent beta-sandwich fold comprised of two beta-sheets. Distant homologues are domains in butyrophilin/ marenostrin/pyrin [1].
PRY is a 50-60 amino acids domain associated with SPRY domains, adjacent to its N-terminal. PRY and SPRY domains are structurally very similar and consist of a beta sandwich fold [1,2,3]. Distant homologues are domains in butyrophilin/marenostrin/py ...
PRY is a 50-60 amino acids domain associated with SPRY domains, adjacent to its N-terminal. PRY and SPRY domains are structurally very similar and consist of a beta sandwich fold [1,2,3]. Distant homologues are domains in butyrophilin/marenostrin/pyrin, evolutionarily more ancient than SPRY/B30.2 counterpart.
