Summaries for ERC1 Gene

Entrez Gene Summary for ERC1 Gene

  • The protein encoded by this gene is a member of a family of RIM-binding proteins. RIMs are active zone proteins that regulate neurotransmitter release. This gene has been found fused to the receptor-type tyrosine kinase gene RET by gene rearrangement due to the translocation t(10;12)(q11;p13) in thyroid papillary carcinoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

GeneCards Summary for ERC1 Gene

ERC1 (ELKS/RAB6-Interacting/CAST Family Member 1) is a Protein Coding gene. Diseases associated with ERC1 include Differentiated Thyroid Carcinoma and Distal Monosomy 12P. Among its related pathways are NF-kappaB Signaling and NF-kappa B signaling pathway. GO annotations related to this gene include PDZ domain binding and leucine zipper domain binding. An important paralog of this gene is ERC2.

UniProtKB/Swiss-Prot for ERC1 Gene

  • Regulatory subunit of the IKK complex. Probably recruits IkappaBalpha/NFKBIA to the complex. May be involved in the organization of the cytomatrix at the nerve terminals active zone (CAZ) which regulates neurotransmitter release. May be involved in vesicle trafficking at the CAZ. May be involved in Rab-6 regulated endosomes to Golgi transport.
