RIPK2

A gene on chromosome 8q21 that encodes a serine/threonine/tyrosine kinase which is intimately involved in modulating innate and adaptive immune responses. Upon stimulation by bacterial peptidoglycans, NOD1 and NOD2 are activated, oligomerise, and recruit RIPK2 through CARD-CARD domains. Once recruited, RIPK2 autophosphorylates and undergoes “Lys-63”-linked polyubiquitination by E3 ubiquitin ligases BIRC2 and BIRC3. The polyubiquitinated protein then recruits MAP3K7/TAK1 to IKBKG/NEMO, induces “Lys-63”-linked polyubiquitination of IKBKG/NEMO and activates IKBKB/IKKB.

In turn, NF-kappaB is released from NF-kappaB inhibitors and translocates to the nucleus, where it activates transcription of myriad genes involved in immune response, growth control or anti-apoptosis. It also plays a role during engagement of the T-cell receptor in promoting BCL10 phosphorylation and subsequent NF-kappaB activation.

The two spreading rates 1 and 3 correspond to chip rates of 1.2288 Mcps and 3.6864 Mcps respectively.
The processing gain GP of a PN receiver depends on the ratio of chip rate and data transmission rate in the measurement channel according to Equation 4.
It consists of a very long sequence of pseudorandom binary biphase modulations on the GPS carrier at a chip rate of 10.23 MHz which repeats about every 267 days.
The spread data rate, known as the chip rate, is fixed at 3.84 million chips-per-second (Mcps).
The chip rate for digital synchronization in a correlating receiver must be the same as in the transmitter to provide the repeatability of the measurements during each search over PN positions.
