Seizure-related 6 homolog (mouse)-like 2 (SEZ6L2) was shown to be involved in transcription of a type 1 transmembrane protein for regulating cell fate. SEZ6L2 was significantly up-regulated in tumour tissues of patients with CRC compared with adjacent normal tissues. Up-regulation of SEZ6L2 was correlated with a poor prognosis in patients with CRC. Furthermore, SEZ6L2 expression was inversely correlated with the expression of cytochrome C in malignant tissues in patients with CRC.

SEZ6L2, also known as PSK-1, belongs to the SEZ6 family. It contains 3 CUB domains and 5 Sushi (CCP/SCR) domains. SEZ6L2 may contribute to specialized endoplasmic reticulum functions in neurons.SEZ6L2 presents on the surface of lung cancer cells. SEZ6L2 should be a useful prognostic marker of lung cancers. Increased expression of this gene has been found in lung cancers, and the protein is therefore considered to be a novel prognostic marker for lung cancer.
