TSC1 - TSC complex subunit 1 Gene
Also Known as LAM; TSC
Species: Homo sapiens
About TSC1
This gene has 47 transcripts (splice variants), 283 orthologues and is associated with 132 phenotypes. Ubiquitous expression in testis (RPKM 9.2), brain (RPKM 8.5) and 25 other tissues.
Summary
This gene is a tumor suppressor gene that encodes the growth inhibitory protein hamartin. The encoded protein interacts with and stabilizes the GTPase activating protein tuberin. This hamartin-tuberin complex negatively regulates mammalian target of rapamycin complex 1 (mTORC1) signaling which is a major regulator of anabolic cell growth. This protein also functions as a co-chaperone for HSP90 that inhibits its ATPase activity. This protein functions as a facilitator of Hsp90-mediated folding of kinase and non-kinase clients, including TSC2 and thereby preventing their ubiquitination and proteasomal degradation. Mutations in this gene have been associated with tuberous sclerosis and lymphangioleiomyomatosis. [provided by RefSeq, May 2022]
