Summaries for LRR1 Gene

Entrez Gene Summary for LRR1 Gene

  • The protein encoded by this gene contains a leucine-rich repeat (LRR). It specifically interacts with TNFRSF9/4-1BB, a member of the tumor necrosis factor receptor (TNFR) superfamily. Overexpression of this gene suppresses the activation of NF-kappa B induced by TNFRSF9 or TNF receptor-associated factor 2 (TRAF2), which suggests that this protein is a negative regulator of TNFRSF9-mediated signaling cascades. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2011]

GeneCards Summary for LRR1 Gene

LRR1 (Leucine Rich Repeat Protein 1) is a Protein Coding gene. Among its related pathways are Antigen processing- Ubiquitination and Proteasome degradation and Immune System. GO annotations related to this gene include isomerase activity. An important paralog of this gene is LRRC58.

UniProtKB/Swiss-Prot for LRR1 Gene

  • May negatively regulate the 4-1BB-mediated signaling cascades which result in the activation of NK-kappaB and JNK1. Probable substrate recognition subunit of an ECS (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins.
