    Summary
    The protein encoded by this gene is a member of the MAP kinase family. MAP kinases act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase targets specific transcription factors, and thus mediates immediate-early gene expression in response to various cell stimuli. It is most closely related to MAPK8, both of which are involved in UV radiation induced apoptosis, thought to be related to the cytochrome c-mediated cell death pathway. This gene and MAPK8 are also known as c-Jun N-terminal kinases. This kinase blocks the ubiquitination of tumor suppressor p53, and thus it increases the stability of p53 in nonstressed cells. Studies of this gene's mouse counterpart suggest a key role in T-cell differentiation. Several alternatively spliced transcript variants encoding distinct isoforms have been reported.

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      Description
      Transcript Variant: This variant (JNK2-g) differs in the 3' UTR and coding sequence compared to variant JNK2-b2. The resulting isoform (JNK2 gamma) has a shorter and distinct C-terminus compared to isoform JNK2 beta2. Variants JNK2-g and 10 both encode the same isoform (JNK2 gamma).

      Status: REVIEWED

      Description
      Transcript Variant: This variant (JNK2-g2) lacks several 3' exons but contains alternate 3' exon structure, and it thus differs in the 3' coding region and 3' UTR, compared to variant JNK2-b2. The encoded isoform (gamma2) has a distinct C-terminus and is shorter than isoform beta2. The 5' UTR of this variant is incomplete due to a lack of 5'-complete transcript support for this variant.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (JNK2-a2) encodes the longer of the two JNK2 alpha isoforms (JNK2 alpha2). The JNK2-a2 variant differs from the JNK2-b2 variant in the use of an alternate internal coding exon of the same length. Thus, JNK2 alpha2 isoform is the same length as JNK2 beta2 isoform, with a few aa differences in an internal protein segment. Variants JNK2-a2 and 8 both encode the same isoform (alpha2).

      Status: REVIEWED

      Description
      Transcript Variant: This variant (JNK2-a1) uses a different acceptor splice site in the last coding exon compared to transcript variant JNK2-a2, resulting in a frameshift and a shorter isoform (JNK2 alpha1) with a different C-terminus, compared to isoform JNK2 alpha2. The JNK2-a1 variant differs from the JNK2-b1 variant in the use of an alternate internal coding exon of the same length. Thus, JNK2 alpha1 isoform is the same length as JNK2 beta1 isoform, with a few aa differences in an internal protein segment. Variants JNK2-a1 and 7 both encode the same isoform (alpha1).

      See identical proteins and their annotated locations for NP_620708.1

      Status: REVIEWED

      Description
      Transcript Variant: This variant (JNK2-b1) uses a different acceptor splice site in the last coding exon compared to transcript variant JNK2-b2, resulting in a frameshift and a shorter isoform (JNK2 beta1) with a different C-terminus, compared to isoform JNK2 beta2. The JNK2-b1 variant differs from the JNK2-a1 variant in the use of an alternate internal coding exon of the same length. Thus, JNK2 beta1 isoform is the same length as JNK2 alpha1 isoform, with a few aa differences in an internal protein segment.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (JNK2-b2) encodes the longer of the two JNK2 beta isoforms (JNK2 beta2). The JNK2-b2 variant differs from the JNK2-a2 variant in the use of an alternate internal coding exon of the same length. Thus, JNK2 beta2 isoform is the same length as JNK2 alpha2 isoform, with a few aa differences in an internal protein segment. Variants JNK-b2 and 9 both encode the same isoform (beta2).
