A ubiquitin ligase complex regulates caspase activation during sperm differentiation in Drosophila.

Cullin serves as a scaffold protein for the assembly of the multisubunit ubiquitin ligase complex that contains a RING domain protein at its C-terminus and a cullin-specific

Sexual differentiation process comprises determining the sexual chromosomes XX or XY + SRY and other genes linked to them, differentiation of gonads in testis or ovary,

The sequence analyses of these proteins show that the Pso2p catalytic core is localized within the N-terminal part of the protein, while a DNA ligase I domain can be detected in the

Background: Considering the similarity between the testis-specific isoform of angiotensin-converting enzyme and the C-terminal catalytic domain of somatic ACE as well as the

responsible for the majority of N-terminal acetylation events: NatA, NatB and NatC [15]. Each complex is composed of specific catalytic and auxiliary subunits. NatB and NatC

Muitos nomes dados aos sítios referem-se às caraterísticas que estas terras têm em relação aos mares ou a fenómenos mineralógicos. Esta área envolvente não

Results: Osteoprotegerin is present in various organs and binds to two ligands: nuclear factor kB (RANKL) related to the differentiation of osteoclasts, and tu- mor necrosis

Objective: To discuss the relationship between testicular microlithiasis and testis tumors in children and to consider the chances of testis preserving surgery in specific
