    • A serine/threonine, FIN13, which includes a collagen-homology domain, an acidic box domain, a catalytic domain, and a putative nuclear translocation sequence. The present invention further relates to the modulation of cellular proliferation, by regulating the activity of the novel serine/threonine phosphatase. Thus, the invention provides the phosphatase, nucleic acids encoding the phosphatase, oligonucleotides specific for such nucleic acids, antibodies to the phosphatase, and method for increasing (or decreasing) the activity of the phosphatase to inhibit (or enhance) cellular proliferation and, thus, tissue growth. Various diagnostic and therapeutic aspects of the invention particularly relate to detection and treatment of hyperproliferative disorders, neoplasms, and tumors. In specific examples, FIN13 is expressed in proliferating cells, notably germ cells of the testes. Increased levels of expression of FIN13 in transfected cells results in a decrease in the cell growth rate.
    • 丝氨酸/苏氨酸FIN13,其包括胶原同源结构域,酸性盒结构域,催化结构域和推定的核易位序列。 本发明还涉及通过调节新型丝氨酸/苏氨酸磷酸酶的活性来调节细胞增殖。 因此,本发明提供磷酸酶,编码磷酸酶的核酸,对这种核酸特异性的寡核苷酸,对磷酸酶的抗体,以及增加(或降低)磷酸酶活性以抑制(或增强)细胞增殖的方法,因此 ,组织生长。 本发明的各种诊断和治疗方面特别涉及过度增殖性疾病,肿瘤和肿瘤的检测和治疗。 在具体实例中,FIN13在增殖细胞中表达,特别是睾丸的生殖细胞。 转染细胞中FIN13的表达水平升高导致细胞生长速率降低。
