PDC may refer to:
Phosducin, also known as PDC, is a human protein and gene. It belongs to phosducin family of proteins.
This gene encodes a phosphoprotein, which is located in the outer and inner segments of the rod cells in the retina. This protein may participate in the regulation of visual phototransduction or in the integration of photoreceptor metabolism. It modulates the phototransduction cascade by interacting with the beta and gamma subunits of the retinal G-protein transducin. By associating with these subunits only, the Transducin alpha subunit will remain active for longer. This will increase the amount of time of visual excitation.
This gene is a potential candidate gene for retinitis pigmentosa and Usher syndrome type II. Alternatively spliced transcript variants encoding different isoforms have been identified.
The PDC (formerly Peel Dem Crew, now Poverty Driven Children) was a street gang based out of the Angell Town housing estate in Brixton, London and is now a music label. Founded by Elijah Kerr, street name Ja-Ja, the gang was originally drawn out of membership of another Brixton crew, the 28s, and engaged in robberies of local businesses as well as drug dealing and firearms, taking control of the Angell Town estate.
Following Ja-Ja's release from prison, he encouraged members of the gang to do more positive things with their lives and start up a music label instead. They released an album, Pray Days Change, and several music videos.
A faction of the PDC meanwhile broke off and converted to Islam in search of an identity while still continuing to engage in crime. This group, known as the 'Muslim Boys', caused something of a stir in the media for their lurid mix of gangsterism and religion and were said to engage in forced conversions at gunpoint.
Sunn amplifiers was a brand of musical instrument amplifiers. Sunn was based in Tualatin, Oregon.
In early 1963, the Kingsmen, a band based in Portland, Oregon, became known for their hit version of the song "Louie, Louie". After its hit single, the band soon embarked on a 50-state national tour. Because the band was used to playing small hops and school dances, many of the members found themselves ill-equipped with the amplifiers that they were currently using. Bassist Norm Sundholm discovered that his bass amp was not nearly powerful enough to play larger concert halls.
Sundholm enlisted the help of his brother Conrad to help solve his problem. By 1964, the Sundholm brothers had designed a high-powered concert bass amplifier. By 1965, the demand for Sundholm's amplifiers had increased to the point where the family garage could no longer be used as the manufacturing facility. Thus, the Sunn Musical Equipment Company was founded.
The band Sunn O))) was named after the company (to the point of including a typographic representation of the logo) and Gross National Productions who were the East Coast promo band for Sunn amps in 1971.

Sunn O))) (pronounced simply sun /sʌn/) is an American drone metal band from Seattle, Washington that formed in 1998. The band is primarily known for its synthesis of diverse genres including drone, ambient, noise, extreme metal and for its extremely loud live performances. Supported by a varying cast of collaborators, the band was formed by two core members: Stephen O'Malley (also of Khanate and Burning Witch) and Greg Anderson (of Goatsnake and Engine Kid).
Sunn O))) is named after the Sunn amplifier brand, whose logo includes a circle next to the "SUNN" banner with waves heading off to the right. In interviews, Stephen O'Malley stated that the band's moniker was also chosen as a play on the name Earth, a band widely regarded as pioneers of drone metal throughout the 1990s. Before the band members moved to Los Angeles, it briefly used the moniker Mars.
The band's style is characterized by extremely slow tempos, heavily distorted guitars, avoidance of rhythm and melody, and alternate tunings. The guitars are notable for their low register, frequently utilising tunings as low as dropped A. Additionally, the band is known for using resonant feedback to create monolithic soundscapes and eerie atmospheres. Percussion is almost never incorporated, with a lack of any discernible beat. When performing live, the band wear robes, fill the air with fog, and play at an extremely high volume.
