What is the function of this protein?
Nuclear envelope protein which has essential roles in assembly of nuclear pore complexes and in chromatin maintenance during the cell cycle (PubMed:16950114, PubMed:16950115, PubMed:26166571, PubMed:27341616).  Appears to be a stable structural component of the nuclear envelope during interphase (PubMed:16950114, PubMed:16950115).  In dividing cells, localizes to kinetochores during early stages of mitosis and then to chromatin during late mitosis (PubMed:16950114, PubMed:27341616).  Important for several mitotic processes including chromosome condensation, kinetochore assembly, chromosome segregation and cell-cycle timing (PubMed:16950114, PubMed:16950115, PubMed:26166571, PubMed:27341616).  In postmitotic cells, plays a role in the early steps of nuclear pore complex assembly by recruiting the nucleoporins npp-10 and npp-5 to chromatin (PubMed:16950114, PubMed:16950115).  Also involved in meiotic chromosome segregation (PubMed:27341616).  May function downstream of the Ran GTPase signaling pathway (PubMed:16950115).
What are the official names of this protein?
Protein mel-28, Maternal effect lethal protein 28.
What are the subcellular locations of this protein?
Nucleus. Nucleus, nucleoplasm. Nucleus envelope. Nucleus inner membrane. Nucleus, nuclear pore complex. Chromosome. Chromosome, centromere, kinetochore. Note=Has a dynamic expression pattern during the cell cycle (PubMed:16950114, PubMed:27341616). During interphase, localizes to nuclear pore complexes and is also found in the nucleoplasm (PubMed:16950114, PubMed:27341616). During early mitosis, localizes to kinetochores in a hcp-3/CENP-A and hcp-4/CENP-C dependent manner (PubMed:16950114, PubMed:16950115, PubMed:27341616). At later stages of mitosis (anaphase), widely distributed on chromatin (PubMed:16950114, PubMed:27341616). During telophase, localizes again to the reforming nuclear envelope (PubMed:16950114, PubMed:27341616).
