O43490 PROM1_HUMAN:

Isoform 1 is selectively expressed on CD34 hematopoietic stem and progenitor cells in adult and fetal bone marrow, fetal liver, cord blood and adult peripheral blood. Isoform 1 is not detected on other blood cells. Isoform 1 is also expressed in a number of non-lymphoid tissues including retina, pancreas, placenta, kidney, liver, lung, brain and heart. Found in saliva within small membrane particles. Isoform 2 is predominantly expressed in fetal liver, skeletal muscle, kidney, and heart as well as adult pancreas, kidney, liver, lung, and placenta. Isoform 2 is highly expressed in fetal liver, low in bone marrow, and barely detectable in peripheral blood. Isoform 2 is expressed on hematopoietic stem cells and in epidermal basal cells (at protein level). Expressed in adult retina by rod and cone photoreceptor cells (at protein level).

描述:
CD133, originally known as AC133. CD133 is a glycoprotein also known in humans and rodents as Prominin 1 (PROM1). Currently the function of CD133 is unknown. It is a member of pentaspan transmembrane glycoproteins (5-transmembrane, 5-TM), which specifically localize to cellular protrusions. CD133 is expressed in hematopoietic stem cells

研究背景

功能:

May play a role in cell differentiation, proliferation and apoptosis. Binds cholesterol in cholesterol-containing plasma membrane microdomains and may play a role in the organization of the apical plasma membrane in epithelial cells. During early retinal development acts as a key regulator of disk morphogenesis. Involved in regulation of MAPK and Akt signaling pathways. In neuroblastoma cells suppresses cell differentiation such as neurite outgrowth in a RET-dependent manner.

翻译修饰:

Isoform 1 and isoform 2 are glycosylated.

Acetylation at Lys-225, Lys-257 and Lys-264 by NAT8 and NAT8B may control PROM1 protein expression and its function in cell apoptosis.

细胞定位:

Fig. 3 CD133 expression was associated with age and prognosis of LARC patients. (a) and (b) Cut-off points for CD133 expression determined by the X-tile program. X-tile analysis divided the entire cohort into the training (shown in the upper-left quartile of A) and matched validation sets (shown on the bottom X-axis of A) based on patient survival data. The black dot in the validation set represents the exact cut-off value for CD133 expression. The entire cohort was divided into low (blue) and high (gray) NLR count groups based on the optimal cut-point, as is shown on a histogram of the entire cohort (b).
