[[http://www.uniprot.org/uniprot/TPR_HUMAN TPR_HUMAN]] Papillary or follicular thyroid carcinoma. A chromosomal aberration involving TPR has been found in papillary thyroid carcinomas (PTCs). Intrachromosomal rearrangement that links the 5'-end of the TPR gene to the protein kinase domain of NTRK1 forms the fusion protein TRK-T1. TRK-T1 is a 55 kDa protein reacting with antibodies against the carboxy terminus of the NTRK1 protein.<ref>PMID:1532241</ref> Involved in tumorigenic rearrangements with the MET.<ref>PMID:2300559</ref>

[[http://www.uniprot.org/uniprot/TPR_HUMAN TPR_HUMAN]] Component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope. Functions as a scaffolding element in the nuclear phase of the NPC essential for normal nucleocytoplasmic transport of proteins and mRNAs, plays a role in the establishment of nuclear-peripheral chromatin compartmentalization in interphase, and in the mitotic spindle checkpoint signaling during mitosis. Involved in the quality control and retention of unspliced mRNAs in the nucleus; in association with NUP153, regulates the nuclear export of unspliced mRNA species bearing constitutive transport element (CTE) in a NXF1- and KHDRBS1-independent manner. Negatively regulates both the association of CTE-containing mRNA with large polyribosomes and translation initiation. Does not play any role in Rev response element (RRE)-mediated export of unspliced mRNAs. Implicated in nuclear export of mRNAs transcribed from heat shock gene promoters; associates both with chromatin in the HSP70 promoter and with mRNAs transcribed from this promoter under stress-induced conditions. Modulates the nucleocytoplasmic transport of activated MAPK1/ERK2 and huntingtin/HTT and may serve as a docking site for the XPO1/CRM1-mediated nuclear export complex. According to some authors, plays a limited role in the regulation of nuclear protein export (PubMed:22253824 and PubMed:11952838). Plays also a role as a structural and functional element of the perinuclear chromatin distribution; involved in the formation and/or maintenance of NPC-associated perinuclear heterochromatin exclusion zones (HEZs). Finally, acts as a spatial regulator of the spindle-assembly checkpoint (SAC) response ensuring a timely and effective recruitment of spindle checkpoint proteins like MAD1L1 and MAD2L1 to unattached kinetochore during the metaphase-anaphase transition before chromosome congression. Its N-terminus is involved in activation of oncogenic kinases.<ref>PMID:11952838</ref> <ref>PMID:15654337</ref> <ref>PMID:17897941</ref> <ref>PMID:18794356</ref> <ref>PMID:18981471</ref> <ref>PMID:19273613</ref> <ref>PMID:20133940</ref> <ref>PMID:20407419</ref> <ref>PMID:21613532</ref> <ref>PMID:22253824</ref> <ref>PMID:9864356</ref>
