Biomarker: SMA

Histology type: endometrial stromal tumor

Country: China

Region: Beijing

Followed up time :

Subgroup 1 name : positive

Subgroup 1 number: 5

Subgroup 2 name: negative

Subgroup 2 number: 13

Conclusion: The histologic features of the metastases may not be similar to those of the primary. SMA is diagnostically useful markers for ESS.

Sample type : tissue

Sample method: immunohistochemistry

Expression pattern : positive expression

Statictics: Mean ;Range

Cohort age: 45;22-75

Funtion Uniprot: Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.

UniProt ID: P63267

UniProt Link: https://www.uniprot.org/uniprotkb/P63267/entry

Molecular function from UniProt:

Tissue specificity from UniProt: In the intestine, abundantly expressed in smooth muscle cells of muscularis mucosa and muscularis propria. Also detected in intestinal vascular smooth muscle cells.

Subcellular UniProt: #Cytoplasm #Cytoskeleton

Alternative name from UniProt:

Cleaved: Cleaved into 1 chains Actin, gamma-enteric smooth muscle, intermediate form

Miscellaneous: In vertebrates 3 main groups of actin isoforms, alpha, beta and gamma have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins coexist in most cell types as components of the cytoskeleton and as mediators of internal cell motility.

Recommended name: Actin, gamma-enteric smooth muscle

Gene name from HGNC: ACTG2 (ACTA3, ACTL3, ACTSG)

HPA class: Disease related genes Human disease related genes

AlphaFold DB: P63267

HPA link: https://www.proteinatlas.org/ENSG00000163017-ACTG2

Tissue specificity RNA from HPA: Tissue enhanced (intestine, seminal vesicle, smooth muscle)

Tissue expression from HPA: Cytoplasmic expression of myoepithelial cells.

Single cell type specificity Group enriched (Breast myoepithelial cells, Smooth muscle cells)

Immune cell specificity: Immune cell enriched (T-reg)

Cancer prognostic summary HPA Prognostic marker in renal cancer (unfavorable)
