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 distal monosomy 12p and breast papillary carcinoma. Among its related pathways are Cytoskeletal Signaling and NF-kappa B signaling pathway. GO annotations related to this gene include Rab GTPase 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.

Disorders for ERC1 Gene


  • Thyroid papillary carcinoma (TPC) [MIM:188550]: A common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. Note=The gene represented in this entry may be involved in disease pathogenesis. A chromosomal aberration involving ERC1/RAB6IP2 is found in cause of thyroid papillary carcinomas. Translocation t(10;12)(q11;p13) involving RET. In vitro, isoform 1, isoform 3 and isoform 5 participating in a ERC1-RET fusion protein activate tyrosine-protein kinase activity.
