POM121 Edit Wikipedia article
Nuclear envelope pore membrane protein POM 121 is a protein that in humans is encoded by the POM121 gene.[5][6][7] Alternatively spliced variants that encode different protein isoforms have been described but the full-length nature of only one has been determined.[8]
Function
The nuclear envelope creates distinct nuclear and cytoplasmic compartments in eukaryotic cells. It consists of two concentric membranes perforated by nuclear pores, large protein complexes that form aqueous channels to regulate the flow of macromolecules between the nucleus and the cytoplasm. These complexes are composed of at least 100 different polypeptide subunits, many of which belong to the nucleoporin family. This gene encodes a member of the FG-repeat-containing nucleoporins. The protein encoded by this gene is an integral membrane protein that localizes to the central spoke ring complex and participates in anchoring the nuclear pore complex to the nuclear envelope.[8]
Antibodies against this protein can be used to identify the nuclear envelope in immunofluorescence experiments.[9]

Structures
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the POM121 domain has been found. There are 2 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
