Summary: This gene is a member of the roadblock dynein light chain family. The encoded cytoplasmic protein is capable of binding intermediate chain proteins, interacts with transforming growth factor-beta, and has been implicated in the regulation of actin modulating proteins. Upregulation of this gene has been associated with hepatocellular carcinomas, suggesting that this gene may be involved in tumor progression. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene have been defined on chromosomes 12 and 18. [provided by RefSeq, Aug 2013]

Findings indicate that km23-2 (DYNLRB2) is required for Smad3-dependent TGFbeta signaling. Km23-2 has functions in TGFbeta signaling that are distinct from those for km23-1 (DYNLRB1).

RefSeqs maintained independently of Annotated Genomes

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.

NM_001319157.2 → NP_001306086.1 dynein light chain roadblock-type 1 isoform d

Status: REVIEWED

Description

Transcript Variant: This variant (7) lacks an exon and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (d) is longer and has a distinct C-terminus compared to isoform a.
