Complement proteins are proteins that play a role in the non-specific immune responses alongside these non-specific immune cells to make up the first line of immune defense. [4] The non-specific immune response is an immediate antigen-independent response, however it is not antigen-specific. Non-specific immunity results in no immunologic memory.
The ETS family is present throughout the body and is involved in a wide variety of functions including the regulation of cellular differentiation, cell cycle control, cell migration, cell proliferation, apoptosis (programmed cell death) and angiogenesis. Multiple ETS factors have been found to be associated with cancer, such as through gene fusion.
The Hox transcription factor family, for example, is important for proper body pattern formation in organisms as diverse as fruit flies to humans. [ 24 ] [ 25 ] Another example is the transcription factor encoded by the sex-determining region Y (SRY) gene, which plays a major role in determining sex in humans.
U6 snRNA is the non-coding small nuclear RNA (snRNA) component of U6 snRNP (small nuclear ribonucleoprotein), an RNA-protein complex that combines with other snRNPs, unmodified pre-mRNA, and various other proteins to assemble a spliceosome, a large RNA-protein molecular complex that catalyzes the excision of introns from pre-mRNA.
The roles of non-coding RNAs: Ribonucleoproteins are shown in red, non-coding RNAs in blue. A non-coding RNA ( ncRNA ) is a functional RNA molecule that is not translated into a protein . The DNA sequence from which a functional non-coding RNA is transcribed is often called an RNA gene .
Short interspersed nuclear elements (SINEs) are non-autonomous, non-coding transposable elements (TEs) that are about 100 to 700 base pairs in length. [1] They are a class of retrotransposons , DNA elements that amplify themselves throughout eukaryotic genomes , often through RNA intermediates.

Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (the brain and the spinal cord) and in the peripheral nervous system that do not produce electrical impulses. The neuroglia make up more than one half the volume of neural tissue in the human body. [1]
