| Description | The TSPAN1 gene is located on chromosome 1 in a 5419 bp sequence (46418799..46424217). The gene contains 10 exons. |
| Transcription | mRNA: 1297 nucleotides in length. |
| Protein |
| Description | 241 amino acids, 26.2 kDa Protein. The 241 amino acid sequence is: 1 mqcfsfiktm milfnllifl cgaallavgi wvsidgasfl kifgplsssa mqfvnvgyfl |
| Expression | Widely expressed. |
| Localisation | Plasma Membrane |
| Function | The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. These are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. |

| Entity | Cervical Cancer |
| Disease | Cervical cancer is a malignant carcinoma or the cervix, typically composed of squamous cells. Most studies have found that human papillomavirus (HPV) infection is responsible for virtually all cases of cervical cancer. |
| Prognosis | Prognosis depends on the stage of the cancer. The 5 year survival rate with treatment is 80 to 90% in patients with stage I disease and 50 to 65% in patients with stage II disease. 25 to 35% of women with stage III cancer and 15% or fewer of those with stage IV cancer are alive after 5 years. Prognosis drops dramatically with tumour metastasis. Thirty-five percent of patients with invasive cervical cancer have persistent or recurrent disease after treatment. |
| Entity | Hepatocellular Carcinoma |
| Disease | Hepatocellular Carcinoma (HCC) is a malignancy of the liver. Most cases of HCC are secondary to either a hepatitis B or C infection or cirrhosis. |
| Prognosis | The prognosis of HCC is dependent on many factors, including tumour size, tumour staging, the involvement of liver vessels, the presence of extrahepatic metastases and the vascularisation of the tumor. |
